When 1,350 joules of heat is added the temperature raises by 3.5 degrees C. A Styrofoam cup calorimeter is calibrated by adding heat to the water in it with an electrical heater. When 1.0 g of NaOH is dissolved in this same calorimeter the temperature raises by 1.6degrees C. Determine the calorimeter constant and the enthalpy of solution for one mole of NaOH.
