3.5 g of a hydrocarbon fuel is burned in a ves-
sel that contains 250. grams of water initially
at 25.00 C. After the combustion, the temper-
ature of the water is 26.55 C. How much heat
is evolved per gram of fuel burned?

heat evolved = q = mass H2O x specific heat H2O x (Tfinal-Tinitial)

heat/g = q/3.5
