A calorimeter contains 25.0 grams of water at the temperature of fifteen degree celsius . When 2.10 grams of a substance ( molar mass =44.0 ) is mixed, it dissolves via the reaction and the temperature of the solution raises to twenty six degree celsius.compute the enthalpy change, , for this reaction per mole.
suppose that the specific heat & density of the resulting solution are equal to those of H2O [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
