3.6 g of a hydrocarbon fuel is burned in a calorimeter that contains a 244 grams of water initally at 25.00 degrees C. After the combustion the temperature is 26.55 degrees C. How much heat is evolved per gram of fuel burned? The heat capacity of the calorimeter (hardware only) is 92.3 J/degrees C

q = heat absorbed by water + heat absorbed by calorimeter.

q = (244 g H2O x specific heat water x delta T) + (92.3 x delta T)

a) q/g = q/3.6g = ?
