Explain the temperature of the solution increases

Reference no: EM13486910

A calorimeter contains 17.0 of water at 12.5 degrees celsius . When 2.10 of (a substance with a molar mass of 80.0 g/mol) is added, it dissolves via the reaction and the temperature of the solution increases to 28.5 degrees. Calculate the enthalpy change, delta H, 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 J/(g*degrees celesius) and 1.00 g/ml ] and that no heat is lost to the calorimeter itself, nor to the surroundings. Express the change in enthalpy in kilojoules per mole to three significant figures.
