in problem six. We find out the number off more soft, William, Guess and we have given volume that is 10,000 Luter. And also pressure is 1. 80 m and the temperature is 10 degrees Celsius. So which we converse in tow. Calvin 2 73 last 10. That means toe 83. Calvin is still temperature off a guess so basically, this question is taken from the topic Ideal guest law. So we can use the ideal gas situation that is PV sickle to NRT in order to find out the number off months off William guests And we know that artist gas constant which its value is 0.8 to 1 later at PM park Calvin Permal So using identical situation. Okay, using ideal guess equation, that is PV physical Tow n rt ive physical to energy where p is the pressure. We is the volume and is the number of small artist gas constant and tasty temperature. So we can put all the values of pressure is 1 80 m volume is 10,000 later. So volume is 10,000 later and number off more. We can we find out and are 0.8 to 1 into temperature is 2 83. So on solving we get number off. More physical toe. 4 30 points. 39 mold and all units are canceled. We get only mold. So number off mall off, William. Guess so we can say that the number off number off malls off. Helium gas is 4 30.39 model. So this is our final answer. So we find out the number off mall off helium guess.

this question is a pretty straightforward ideal. Got Gaskell equation. First thing you need to do is to turn our 35 degrees Celsius into Calvin. So do that. We take 35 plus 2 73 So 35 Celsius is equipment of 308 health. Next, we have to look at her ideal gas law equation unsolved for we&#x27;re looking for in the malls. That&#x27;s gonna be peopIe divided by Greek times. Time. Now we just plug in. We&#x27;re given 3.1 18. Mr. Pressure won&#x27;t apply that by 2 22 years. It&#x27;s very that was the table Divide that by the three point into your 83 times the temperature just 308 So it&#x27;s everything and the top right about everything on the bottom. When we saw that we get 2.7 rules. The answer, according to thes parameters, is 2.7 months

Hello Today we&#x27;re here to talk about Chapter 12 Question 55 which asks us to consider a large polyethylene weather balloon here. We&#x27;ll put a little basket under it, So could be someone writing in our little weather balloon. Hello. And so this balloon is that a temperature presently of 20.0 degrees Celsius? And we also have a pressure inside the balloon. So 20 point cereal degree Celsius and the pressure is equal to 94.0 k p. A. And lastly, the balloon has a volume of 65 leaders. Now, this probably isn&#x27;t actually enough to lift a person. This is helium, But that&#x27;s okay. We want to determine the number of moles of helium in the balloon. Since helium is pretty expensive and we&#x27;re gonna choose a gas constant that will allow us to relate Kilo Pascal&#x27;s and leaders just going to be 8.314 Leader K P. A. We can look this value up in a table. This per mole Kelvin, and this should tell us that we need to have a temperature that&#x27;s in Kelvin rather than in degrees Celsius. And so if we just add 273 Tore Celsius number. We get Kelvin 293 Kelvin. And now if we just write out our ideal gas law, PV equals N r T. We can see there were ready to solve for end. So if we just divine both sides by r T, we can rewrite the equation. PV over R T is equal to end, and we can start writing this out with our numbers. We have 94.0 k p a Times 65 leaders divided by 8.314 Leader K p A. Per mole Kelvin Times air temperature 293 Kelvin. There always has to be Kelvin absolute temperature and so we can find that we have an answer of 2.51 moles of helium. And so hopefully this helps you become a little bit more comfortable using the ideal gas law to determine ah amounts of moles of a gas given temperature pressure and volume. And just let&#x27;s finish this off by converting this to 2.5 moles of helium and account for our significant figures. 2.5 miles of helium in our weather balloon

All right, So this question is asking us to find the number of molds of helium that can fill a canister. You know, the volume of the canister is 43.8 leaders that we have 1.51 times 10 to the fourth killer Pascal&#x27;s for our pressure, and the temperature is 25 degrees Celsius. So we&#x27;re gonna look for an equation that can relate pressure, volume, temperature and number of malts. And that equation is the ideal gas law. PV equals in our tea. And so we&#x27;ve got everything accounted for. Our is a constant, so we don&#x27;t have to worry about not knowing that because we always know the value for artists constant. So I&#x27;m going to start by rearranging this equation. I want to get end by itself, because that&#x27;s what we&#x27;re solving for. So I&#x27;m gonna divide both sides. Bye, Artie and I get in is equal to P V, divided by Artie. And now that I have that, I could go ahead and start filling in some numbers. Soapy is 16,000 sees me 100 killer Pascal&#x27;s. The volume is 43.8 leaders, and then we&#x27;re gonna divide that by our and the value for our depends on which unit you&#x27;re using for pressure. In this case, we&#x27;re using Killa Pascal&#x27;s. So our is equal to 8.31 leader Killa Pascal Mole killed. So we&#x27;re gonna put in 8.31 down here and for a temperature, we&#x27;re gonna need to convert that a little bit.

GTO be going over. Question number two I eat Mr X. Oberle come burning rooms. Two moles. So, in order to cover grams to moles, you would need to give I by the molar mass of your element or come from. So you have helium. We have point me color. You have 0.46 grounds of helium. Your thing for every one moon of he knew. You have four grooms of helium. Then when you dry weight, when you drive for 4654 you get that you have a 0.11 fine moves off here.

So in this question, were given a pressure, volume and temperature that are changing but an amount of gas, and that is constant. And so we have a relationship that derives from the ideal gas. All this is, I think, commonly called the combined gas law. Um and so it says that p one z one over t one equals p two. Easy to over teacher, meaning at one point in time, like we have all of these conditions and another point time. We have all of these conditions. So if we have five of these six variables confined last one and so this commune derived from the ideal gas law, doing so is a good exercise. So now I&#x27;m gonna right over here on this side what information we&#x27;re given. We&#x27;re told that the initial pressure is one atmosphere. The final pressure, we&#x27;re told, is 200 tour or 220 tour. The initial volume were given is one leader, and the final volume is what we&#x27;re looking for. And finally, we&#x27;re told that the initial temperature is 23 degrees Celsius in the final, temperature is negative, 31 degrees Celsius. And so we&#x27;re gonna need to convert units to be a little bit nicer here. And so that&#x27;s what we&#x27;re going to do. Um, apartment. Okay, here we go. And so for the pressures, we want them both to be anonymous years. So pressure one, it&#x27;s still gonna be equal to one atmosphere. The pressure to we wanted to go from 220 tour. So atmospheres and the conversion for that used to divide by 760. If you&#x27;re not sure how this is done, go back and do some of the previous problems about unit conversions for pressures. But either way, if you divide 220 by 760 you&#x27;re going to get 0.28 94 amateurs. The volumes air fine. We have those. Volume one equals one leader. Volume two is what we&#x27;re looking for. Now both the temperatures need to be turned into Calvin and so t one. So we&#x27;re going to add 273 teach these values and so t one has been become 296. Calvin and T two is going to be 242 Calvin. And so now we plug in thes five values into this equation. find the six months. So we&#x27;re going to have P 11 atmosphere. I&#x27;m gonna ignore the units. For now, we&#x27;re already written the mountain a lot. One leader over to 96 equals P P two, which is point to a 94 times of U two, which is what we&#x27;re looking for. Over 242 Calvin. And so if you solve all that going to get that V two is equal to 2.8 Julius Mr Final Answer.
