Question

three containers of equal volume are filled with Xenon, Carbon Dioxide and air ( 78% N2, 21% O2, 1%Ar). (all containers are at the same P and T). Which container has the most "gas particles"? which has the least? (in the context a gases, we often use "molecules" to mean generic gas particles that is, it includes single atoms for noble gases). which has the most mass? which has the least? which has the most number of atoms? which has the least ? which has highest density? which has the least? Do the most atoms always correspond to most mass?

Explanation / Answer

lets suppose p=1 atm and t=0oC

xenon density= 5.89 g/l

CO2=1.977 g/l

air=1.299 g/l

so xenon has the highest density and air has lowest

now

as density= mass/volume

since volume is constant here. so density is directly related to mass...thats why xenon will have most mass and air have lowest mass

for number of atoms multiple the number of moles of each gas with avegadro number(mole=mass/molar mass)

xenon will have most number of atoms.

yes most number of atoms mean more mass
