calorimeter contains 16.0 of water at 12.0. When 1.20 of (a substance with a molar mass of 68.0 ) is added, it dissolves via the reactionand the temperature of the solution increases to 28.5.Calculate the enthalpy change, , 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 and 1.00 ] 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 Calculate the enthalpy change, , 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 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings
