Acalorimeter contains 20.0 ml of water at 15.0 °c . when 1.50 g of x (a substance with a molar mass of 76.0 g/mol ) is added, it dissolves via the reaction x(s)+h2o(l)→x(aq) and the temperature of the solution increases to 25.0 °c . calculate the enthalpy change, δh, for this reaction per mole of x. assume that the specific heat of the resulting solution is equal to that of water [4.18 j/(g⋅°c)], that density of water is 1.00 g/ml, and that no heat is lost to the calorimeter itself, nor to the surroundings.(a) express the change in enthalpy in kilojoules per mole to three significant figures. (b) determine the masses of titanium and iodine that react if 1.59×10^3 kj of heat is emitted by the reaction. (c)express your answer to three significant figures and include the appropriate units.
