Heat lost in a system can be calculated by multiplying the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = C (T2-T1)

Heat = (3.03) (1.252)

Heat = 3.79 kJ / mol of heat is liberated

When 0.1625 g of magnesium is burned in a bomb calorimeter that has a heat capacity of 3.03 kJ / ∘C, the temperature increases by 1.252 ∘C. How much heat (kJ/mol) is liberated during the burning of the magnesium?
