A styrofoam cup calorimeter is calibrated by adding heat to thewater in it with an electrical heater. When 1,350 J of heatis added the temperature of the calorimeter raises by 3.5 degreesC. When 1g of NaOh is dissolved in this same calorimeter the temperature raises by 1.6 degrees C. Calculate the calorimeter constant and enthalpy of solution for one mole of NaOH.
