Question

A mixure of gases contains Nitrogen and Hydrogen. The mixure has a pressure of 1.070 bar and it's density is 0.5122 kg/m3. Assume the gases are ideal.
What is the mole fraction of Nitrogen gas in the mixture?
Thanks a lot

Answer 1

pV=mRT/M

M=mRT/pV=nu RT/p

K(N₂)M(N₂)+(1-K(N₂)M(H₂)=₰RT/p

28K+2-2K=512.2g/Mol*8.314J*Mol*K*T

K(N₂)=0.039798T-2/26…

Next, you need to set the temperature
