Hello everyone, let's start the question.
00:03
In this question we are given with two cylinders a and b which has hydrogen gas and methane gas present in them respectively.
00:13
We have the pressure volume and temperature conditions for the two which are similar as the pressure is 1 .2 atm, volume is 1 .25 liters and temperature is 293 kelvin.
00:30
In this question we are asked to determine the number of moles of a and b.
00:36
So now let's use the ideal gas equation, ideal gas equation for which we know it has the expression as pv is equal to nrt.
00:53
Here p stands for pressure, v denotes the volume, n stands for the volume, n stands for the number of moles r stands for gas constant and t denotes the temperature.
01:18
So now the value of r is 8 .314 joules per kelvin per moon.
01:29
So now if we substitute the respective values here the value of n will come out to be equal to p multiplied by v divided by r multiplied by t...
