Hello, i'm starting my studies about gases and one question left me in doubt:

A mixture of H2 (g) and N2 (g) has density of 0,216 g/L at 300 K and 500 torr. What's the composition in molar fraction of this mixture?

MMH2 = 2,016 g/mol

MMN2 = 28,014 g/mol

Thanks in advance!

Hint: can you think of a way of expressing the mixture density as a function of its composition?
