Question: Consider a mixture of two gases A and B. Show that when the mass fraction xA and xB are known, the mole-fraction can be determined

Consider a mixture of two gases A and B. Show that when the mass fraction xA and xB are known, the mole-fraction can be determined from yA = MB / [MA (1/xA- 1) + MB] and yB = 1 - yA where MA and MB are the molar masses of A and B.
