Question

What is the mass of `8.01*L` of chlorine gas at `"STP"`?

Answer 1

Well the molar volume at `"STP"` is `22.4*L`, depending on your syllabus....

Explanation:

And so we have a mass with respect to chlorine gas of....

`(8.01*L)/(22.4*L*mol^-1)=0.358*1/(1/(mol))=0.358*mol`

And thus a mass of `0.358*molxx70.9*g*mol^-1=25.4*g`..

Note that chlorine, as are ALL the elemental gases with any chemistry, is BIMOLECULAR, i.e. `X_2`...
