so in problem seven we used the concept off the ideal gas equation, which is equal toe PV physical tow n rt, which is known as the ideal gasification. So in this question, we find out three ways that our guests pressure is 0.50 8 p.m. And we have given the volume that is 22.4 later and one mole at STP condition. So basically, the STP condition is this standard temperature and pressure condition in which the pressure is 18 p. M. And the temperature is zero degrees Celsius or 2 73 Kelvin. So the three ways that we can find we can get up. Gas pressure is 0.508 p. M. So So from this idol, guess equation be physical to energy. So we can use P because we find out the pressure p so into 22.4, then zero point five moles on and this is 0.8 to 1, which is value off our and temperature is 2 73 Kelvin. So on solving we get a pressure is 0.508 p. M. So this is one way The another way is that pressure in tow continue to 0.4 later one into one more into 0.8 to 1 into 1 37 Calvin that men would use a temperature is 1 37 Calvin in this case, so we get a pressure is equal to 0.508 p. M. And in the third case, pressure into volume is 44.8 and number off Molly&#x27;s one in 20.8 to 1 in 2 to 73 Calvin. So we get a pressure. It&#x27;s 0.50 PM in this case also, so that means there is the three ways that we can use. So first is reduced the number off particles to 0.5. Reduce the number off particles so 0.5 mall. So this is first way and second is reduced. The temperature produced the temperature toe 1 37 Calvin and the third ways increase The volume to 44.8 later increased the volume to 44.8 later. So these are the three weeks from which we get the pressure off. 0.508 p. M. which is asked the question. So that means when we use number off Molly 0.5, then Second case in the second case temperature we can use is 1 37 Calvin. And in the third case, volume is used 44.8 later. So from all these case, we get up. Pressure is 0.508 p. M. So this is the case. One. This is the case number two, and this is the case number three.

question 48. One more gas. Coco pie. You falling off 20 to 1 for the attack. That&#x27;s a context for that extremes to plan for data. I&#x27;m thirsty. That song with I&#x27;m really temperature and pressure conditioning. Just a free two more off the cast into 22. Want for later. Okay, now I will say right. He&#x27;s on the first condition is one more, and it cost a lot more on one of the cast for them will be And two point for data. I&#x27;m not stp temperate. Terry&#x27;s to 10. Stand out that vato referees time that. But doctors found out close today Exact condition. I want a complete it temperature pressure happily imprison her competition and they want a cup of tea. P m e. Call it t to pay too good toe feet two more And it will be two more. If only they had to sign for later. Okay. Ali used the one you want. Okay. Now, teensy, he was in party, so all right, be different. I t defied by t egos and Oh, really? So for the first condition Yeah, well, look, there is always a constant the fire fighting form. No What? So this is the 1st 1 Ghetto one. Not most last father went too far. Ita cost more. Thanks. Uh, which is times? Times t 2 73 Every. So the 2nd 1 along too far. Let&#x27;s see. Hey, hey. Two But by the forum trying to plan for leader This is two more. Uh, I asked to 73 No thanks to you too. Okay, so if I make are my son gets here, My heart will be wonderful. Yeah. Time spending to find 45 by? Well, well, after 73 now I&#x27;ve substitute funded far happy two times tended to find for later He lasted two more. Uh, what is going on? Cost tapping to find phone get Bye bye. No, 2 73 And fast into now. My pee too. If I take to It&#x27;s his father to Mark. Oh, and I want more to Santa today. You got to fight for So it&#x27;s going to be to fight some south Terry to sound really camping. So the condition for this is sid away. We fixed it, their pressure constant. And then on the pressure it&#x27;s doubled. The pressure is double. So the condition now if 10 creature team too. You need to 73 because it&#x27;s simple enough to you are found in our P too. Maybe two more. We just took times Toso with double. Just tell her cracker. Ah, kid preacher. All right. 2 73 people, huh? Dances, new temperature, pressure, condition Anything could fit two full of cats into a forum of trains to point for later.

Farhanul Hasan · Answer

all right. This really is from the definition of all um which which you confined from which you can derive from of of God. Rose Law states that equal volumes of all gases of the same temperature and pressure have the same number of molecules, right? One mole, therefore will have the same volume. And this is one more off any gas. As a matter of common dioxide oxygen, hydrogen methane will have the same volume of standard temperature and pressure conditions. So we know that TV he calls and r t bait and being the number of calls on DSO volume is an r t overpay. And so now, for one mole of gas under standard conditions, uh, are is a constantly at 8.3, Standard Commissioners has temperature of 2 to 73.15 Calvin on and pressure of about 1.1 times 10 to the five past house. These are alas, I units, and what you get is a volume off about 0.0 2 to 4 meters cubed to multiply by 1000 to get 22.4 leader. So that&#x27;s the amount. That&#x27;s the volume of gas volume contained volume of gas and one mole, uh, under of standard conditions, standard temperature and pressure for any guests. And it just comes from of God. Rose law in the definition off the wall.

Hugh Ross · Answer

all right. Standard temperature and pressure is when the temperature is zero degrees Celsius and the pressure is 101.3 kill of Pascal&#x27;s. So we&#x27;re asked to find the volume occupied by one mole of ideal gas at standard pressure. So we know that that let&#x27;s start out with the perfect gas law PV equals and our tea and were asked to calculate the volume. And when you&#x27;re doing calculations, always isolate the variable that you&#x27;re looking for, which is volume. And do this symbolically. Please do not try to plug in numbers before you isolate your very well. Make your professor or your teacher happy. All right, so now let&#x27;s plug in what we know. We know that there&#x27;s one mole of gas, which we know is 6.22 times 10 to the 23rd molecules. But that&#x27;s not needed here, since we already and Little N is the number of bolts. Are is Thea Perfect gas constant, which is 8.31 and that has some units of jewels. Her mole Kelvin. All right, which means when we plug in a temperature, it better be in Kelvin and the reason temperatures in Calvin because it&#x27;s directly proportional to pressure when it&#x27;s in Kelvin when it&#x27;s in Celsius, that just doesn&#x27;t work in zero degrees. We know that the Kelvin temperature is equal to the Celsius temperature plus 273. So our temperature zero degrees Celsius If that zero we&#x27;ve got 273 Copan. All right, so next we&#x27;ve got we&#x27;ve got a divide by the pressure. Now the standard unit for pressure is past scales and were given kill a pass scales so we&#x27;ll have to convert. So 101 0.3 Killa kilo is times tended third and pressure is in units A Pascal is is in units of of Newton&#x27;s of force for every square meter of pressure. Okay, so let&#x27;s see what we can cancel from From this we can the mole&#x27;s cancel Kelvin&#x27;s cancel. Okay, Now a Jule is, um is a Newton meter by definition, so the Newtons cancel and then the meter&#x27;s flip up for the dominator. If you invert by the by am the reciprocal multiplied by the reciprocal that is we had of getting cubic meters, which is good news because we&#x27;re finding volume to run those numbers in your calculator, and you should get 0.2 to 4. We&#x27;ve got 366 I am number balls never are considered a limiter to your sig figs. So here we go. That&#x27;s our answer them our calculations. So this will not limit our sig figs of our answer. And ah, but we have 33 and 466 we round to the least number of sig Figs. So we have 366 on her answer. So that is our calculation for our volume at standard pressure and temperature.

this question asked us to use the ideal gas law to show that the molar volume of a gas at FTP it&#x27;s 22.4 leaders. So STP stands for standard temperature and pressure and that is a temperature of 2 73 Calvin and a pressure of one atmosphere. So I&#x27;m gonna use the ideal gas law. As they said, which is p The equals N r T P is pressure. The is volume and is the number of moles are is a constant and then t is temperature. So here we have a Well, we&#x27;re looking we&#x27;re gonna look for volume. We&#x27;re gonna prove that we get a falling equal to 22.4. But we have pressure and temperature over here and for N. We&#x27;re going to use one since the molar volume of gases, the volume per mole. So we&#x27;re just going to use one to make it easy. So if I have my one atmosphere of pressure, I&#x27;m looking for volume here. Um, are you use one mole and then our is a constant. It&#x27;s 0.8 to 1 leader atmosphere per mole, Calvin and then my temperature is to 73 k at SCP. So if I do this math, um, point only to one times 2 73 is, um equal. Teoh 22.4. Now the mole here and we&#x27;ll hear will cancel the Calvin here, and Calvin here will cancel. And then my one atmosphere We&#x27;re here by divide 22.4 by one. I get 22.4. So the atmosphere cancels there and we have ah unit of leader left over and my V equals 22.4 leaders. So one mole of the gas under these conditions is going to equal are going to have a volume of 22.4 leaders.

Zoe Kalbag · Answer

standard temperature and pressure, or S T P is defined as one standard atmosphere of pressure or one ATM and zero degrees Celsius or 273 Kelvin. And this is an important reference condition because a lot of the chemical and biochemical processes that we learn about take place around one atmosphere of pressure and close to this temperature. So in order to find the volume of one mole of gas at standard temperature and pressure, we will use our ideal gas law equation. PV equals NRT. And since we&#x27;re solving for volume, we can quickly rearrange this equation by dividing both sides by pressure. And then we will just plug in our values. So for and we have one mole of gas for our we&#x27;re using the universal gas constant with the appropriate units because we&#x27;re using atmospheres of pressure, we will be using our absolute temperature in Calvin and the pressure of one atmosphere. And with this we get a volume of approximately 22.4 leaders and this number is considered our Moeller volume because according to the ideal gas law, it is the volume of one mole of gas. Understand
