Hi, so we are to identify which gas sample would have the largest volume based on the given amount.
00:09
So it is said here that all samples will have same temperature and pressure.
00:13
So let's assume that we have stp, so that means standard temperature and pressure.
00:20
So our temperature will be 273 kelvin and then pressure will be 180 m.
00:27
So for this we will be using the ideal gas law equation that's pv is equivalent to nrt.
00:35
Alright, so rearranging this to solve for volume, we're going to have nrt over the pressure.
00:41
Now let's calculate the first given volume will be equivalent to n.
00:45
We have 65 .7 grams of xenon.
00:50
We need to convert this to moles by dividing the atomic mass of xenon that's 131 .29 grams here and then we have moles in here.
00:59
R is the gas constant 0 .0821 liters atm per mole kelvin and then our temperature we have assumed 273 kelvin.
01:11
Pressure is 180 m...
