Agas mixture consists of 7 lbm of o2, 8 lbm of n2, and 10 lbm of co2. determine (a) the mass fraction of each component, (b) the mole fraction of each component, and (c) the average molar mass of the mixture. 2. determine the binary diffusion coefficient of o2 in nz at the following conditions (assume the mixture is dilute for all cases): (a) 200 k and 1 atm, (b) 400 k and 0.5 atm, and (c) 600 k and 5 atm.
