A fluid flows through a pipe with a mass flow rate of 350kg/min, with the following compositions: 20 mol\% methanol 80mol% water Calculate: a. Average molecular weight of the fluid kg/kmol b. molar flow rate of the stream kmol/min c. Molar flow rate of the stream lbmol/min d. The mole fraction of each species in the stream (in lbmole/lbmole): methanol: H2O e. The mass fraction of each species in the stream (in lbm/lbm): methanol: H2O f. The mass fraction of each species in the stream (in g/g ): methanol: H2O
