A calorimeter contains seventeen mili litres of H2O at fifteen degree Celsius temperature. When 2.30 grams of A with a molar mass of 44.0g/mol is mixed, it dissolves through the given reaction A(s)+H20(l) ----> A(aq) and the temperature of this rises to twenty nine degree celsius. compute the enthalpy change, (Delta H), for this reaction per mole of A. suppose that the specific heat =[4.18J/(g*Degrees C) and density=1.00(g/mL)?
