Posted by Stephen on Thursday, April 8, 2010 at 11:18am.

In an experiment, 230 kJ of heat energy are released to the surroundings when steam is converted to liquid water. Calculate the number of grams of water condensed. The following data may be of use:
vap = 2260 J/g; Hfus = 334 J/g; Cp(ice) = 2.06 J/g C; Cp(water) = 4.18 J/g C;
Cp(steam) = 1.99 J/g C
