I have a question where I am given a sample of a mixture of gases (C2HF5 and C2H3F3) and was told to find the volume percentage of one gas.
Pressure = 0.449 atm
T= 288.15 K
Density= 1.79 g/L
I have also found the average molecular mass to be 94.266 amu.
So how can i approach this question to find the volume percentage of C2H3F3?
Do i use PV=nRT?
