< 9 of 13 Review Constants Periodic Table Part A A calorimeter contains 28.0 mL of water at 11.0 °C. When 250 g of X (a substance with a molar mass of 60.0 g/mol) is added, it dissolves via the reaction X(s) + H2O(1) X(aq) and the temperature of the solution increases to 30.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that...
