A calorimeter contains 29.0 mL of water at 13.0 degrees celcus When 2.50 of (a substance with a molar mass of 57.0 ) is added, it dissolves via the reaction and the temperature of the solution increases to 28.0.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
