A mass m = 0.052 kg of benzene vapor at its boiling point of 80.1 C is to be condensed by mixing the vapor with water at 44 C.

A mass m = 0.052 kg of benzene vapor at its boiling point of 80.1° C is to be condensed by mixing the vapor with water at 44° C. What is the minimum mass of water required to condense all of the benzene vapor? Assume that the mixing and condensation take place in a perfectly insulating container.
