H2o has a mc021-1.jpghvap = 40.7 kj/mol. solve for the quantity of heat released when 27.9 g of h2o condenses.
a) 60.00 kj
b) 61.05 kj
c) 63.09 kj
d) 68.60 kj

The heat released for a certain mass of water that is condensing is calculated by multiplying the heat of vaporization and the amount of the substance. Calculation is as follows:

Heat released = (40.7 kJ/mol) (27.9 g) ( 1 mol / 18 g) = 63.09 kJ

Therefore, the correct answer from the choices listed above is option C.

The equator absorbs the most sunlight
