A calorimeter contains 32.0mL of water at 11.5 ?C. When 1.60g of X (a substance with a molar mass of 50.0 g/mol) is added, it dissolves via the reaction X(s)+H2O(l)?X(aq) and the temperature of the solution increases to 30.0 oC. Calculate the enthalpy change, ?H, for this reaction per mole of X. Ignore any heat transfer to or from the calorimeter.
