Problem- Consider a mixture of argon and helium. The density of the mixture measured at t=22.8 C and p=791 torr, is d=0.662 g/L. What is xar, the mole fraction of argon in the gas mixture? You may assume that argon and helium behave ideally for the conditions in the problem.
Explain and show all work please.
I want you to elucidate the chemistry in this above problem.
