A calorimeter contains 26.0 of water at 12.0. When 1.40 of (a substance with a molar mass of 79.0 ) is added,
it dissolves via the reaction 3 and the temperature of the solution increases to 29.0. 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.
