(b) if 1. tainer initially containing 100.0 g of h20, what is the final temperature of the water? use c = 4.18 j/g°c and = 43.99 kj/mol at 25.0°c. the vapor pressure of h20 at 25.0°c is 23.77 torr; assume it remains constant throughout the tem- perature change of the liquid. - cat. 00 g of h20 evaporates at 25.0°c in an adiabatic con- vap
