When 32.4 g of water vapor condenses, how much heat is given off? The heat of vaporization for water is 40.67 kJ/mol.

May 13th, 2015

Heat released by condensation of water = No of moles of water x  Heat of vaporization of water.

Moles of water =  mass of water divided by its molar mass.

Mass of water = 32.4 grams,

molar mass of H20 = 2(1) + 16 = 18 grams

Moles of water = 32.4/18 = 1.8 moles

Heat of vaporization of water = 40.67 kJ/mol

So heat released = (1.8 x 40.67) kJ/mol

=  73.206 kJ.

Hope this helps! Please best me if it does or ask any question if you are not satisfied!
