A calorimeter contains 24.0 mL of water at 11.5. When 1.50 of X (a substance with a molar mass of 82.0g/mol ) is added, it dissolves via the reaction


and the temperature of the solution increases to 28 C.
Calculate the enthalpy change, , for this reaction per mole of .

Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
