Calculate the enthalpy change for this reaction per mole of


A calorimeter contains 34.0 mL of water at 12.0 C. When 1.20 g of "X" (a substance with a molar mass of 63.0 g/mol ) is added, it dissolves via the reaction and the temperature of the solution increases to 29.0 C.

X(s) + H2O(l) >>> X (aq)

Calculate the enthalpy change 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*C and 1.00g/mL ] and that no heat is lost to the calorimeter itself, nor to the surroundings
