I dont think there's a quicker way to work these out. My Chem teacher said the multiple choices are often difficult and a mix of prior knowledge and using common sense to eliminate and working stuff out individually. We were told to do these at the end as they take time and aren't worth as many marks. I haven't worked out the answer but they are just time consuming. Sorry if that didn't help

This ones pretty quick. Like the user above said equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. So just do (volume/50)*molar mass and compare. The largest is 150cm3 of N2 with 84 and second is 200cm3 of Ne with 80.8. These arent the actual masses, just relative so we can compare.
