V, and I must all be constant pressure 3 point To a calorimeter containing 300.0 g of water at 20.00', 10.65 g of NaOH, also at 20.00'C was added. The temperature of the solution, increased to 28.50 c. If the specific heat of the mixture is 4.184 Jg* °, and the small heat capacity of the calorimeter is ignored, what is the heat evolved, per mole of sodium hydroxide? 45.5 -37.4 kJ 415 kJ -153 kJ 90.5 kJ
