Good day.

If we suppose a gas sample behaves as an ideal gas, then we can relate the pressure, volume, temperature, of a certain amount of gas using the ideal gas law, where p is the pressure in atm, n is the number of moles.
00:18
R is the gas constant, which can be equal to.
00:23
So if the combination is pressure is atm and volume is liters, then the gas constant is equal to 0 .0.
00:34
821 litre atm per mole kelvin with of course temperature that is expressed in kelvin so in this problem let us assume that the sample is a behaves as an idea class and we want to know for letter a the volume of the sample given with the number of moles being equal to 1 .35 the pressure being equal to 1 .29 atm and the temperature being equal to negative 6 degrees celsius.
01:25
Let's introduce what you are going to find for letter b as we go on there.
01:30
So first that has rearranged this equation the ideal gas law in order to express v in terms of the other variable.
01:39
So we have b equals.
01:41
Nrt over p.
01:43
So let us take note that we have to express temperature in terms of kelvin...
