What is the total pressure inside the cylinder? 6.7 atm What is the mole fraction of N2 in the mixture? 0.52 atm

Anonymous · Answer

P V = n R T V, T and R are the same for each so n, the number of mols is proportional to P total pressure = 3.5 + 2.8 + .25 + .15 = 6.7 so for example mol fraction of N2 = 3.5/6.7 = .522
