How much energy is released when 13.3g of steam at 121.0 degrees C is condensed

Question

How much energy is released when 13.3g of steam at 121.0 degrees C is condensed to give liquid water at 80 degrees C? The heat of vaporization of liquid water is 40.67 kJ/mol, and the molar heat capacity is 75.3 J/(K x mol) for the liquid and 33.6 J/(K x mol) for the vapor.

Explanation / Answer

NOTE: suppose we are working with 1 atm...

m = 13.3g vapor

T1 = 121
