A calorimeter contains 17.0 mL of water at 15.0 degrees celcius When 1.40 g of (a substance with a molar mass of 69.0 g/mol) is added, it dissolves via the reaction X(s)+H2O(l)->X(aq) and the temperature of the solution increases to 28.5 degrees celcius. Calculate the enthalpy change, Change H, for this reaction per mole of X. Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 J/(g*degrees celcius) and 1.00]g/mL and that no heat is lost to the calorimeter itself, nor to the surroundings.
