When you enter these values, the molar mass is Chemical Engineering. (v) Boron trichloride at 420 K where Psat=23. 8 cmy/mole and Tb=239. For saturated liquid ammonia at 270 K, V^= 1. Assume V doesn't change with pressure. For liquid water the molar heat capacity at constant pressure C. pp ig in lh lb lr kb lf bq wu
