#56425J# or #56.425kJ#

Explanation:

At the same temperature (100'C) the conversion from vapor to liquid (condensation) requires removal of the heat of vaporization without worrying about specific heats in either phase.

The heat of vaporization of water at normal pressure is# 2257 J/g#

#25.0g xx 2257J/g = 56425J# or #56.425kJ#
