actually the trick is that they have already given partial pressures you dont need to calculate mole fraction, total pressure is equal to sum of partial pressures- for mass, you just use PV=nRT here p is partial pressure, and calculate each ones mass

using PV=nRT,u have to determine the Mm of each gas
