So here in this question it is given that the volume is 16 .4 emil, so we need to convert this in terms of liter.
00:08
So this will be equal to 0 .164 liter when we divide this value by thousand.
00:15
So we'll get the value of volume equal to this.
00:18
Then the temperature is given as 22 degrees celsius.
00:22
We need to convert this in terms of kelvin.
00:24
So here we'll write 22 plus 273 kelvin.
00:28
And the answer that we'll get for the temperature is 295 .15 kelvin and the pressure is given as 659 tor.
00:39
Now we need to convert this in terms of atm.
00:42
So what we know is that 760 tor this is equal to 1 atm.
00:52
So from this we can write that 659 tor this will be equal to 1 atm.
00:59
1 divided by 760 multiplied with 659 and this will give us the value of pressure as 0 .867 atm.
01:15
So this is the pressure.
01:17
Now we also know that the value of r is equal to 0 .0821 liter atym, kelvin inverse mole inverse so using these values now we will write the ideal gas equation that is pv equal to n r t n that is number of moles first so in the next step we can write that n is equal to pv divided by r t so let us put the values here the value of p is 0 .867 atm this is multiplied with the value of v which is 0 .0164 liter this is divided by the value of r which is 0 .0821 litre atm kelvin inverse kelvin inverse this is multiplied with the value of t that is temperature which is 295 .15 kelvin...
