A gas mixture consists of 0.62 percent N2 and 0.38 percent CO2 by mole basis. Take 1 kg mole of the mixture and the molecular weigh of N2 and CO2 are 28 and 44 kg/kg.mol respectively. Determine the (i) mole fractions of the constituents, (ii) mass fractions of constituents, (ii) the average molar mass of the mixture, and (iv) the average gas constant of the mixture. Take universal gas constant is 8.314 kJ/k mole.K.
