How much heat is required to raise the temperature
of exactly one liter of water fro m 60 °F to 180 °F?
answer: 279 kj/mol

Convert 60 F to C. Convert 180 F to C.
q = mass x specific heat x (TfinalTinitial).
Tf and Ti to be in celsius.
mass of 1L H2O = 1000 g.
The answer is not right. The answer is 279 kJ (for 55.5 mol) and not 279 kJ/mol. 
I just copied the units wrong from the practice test we have.
