3. When 1.38 g of liquid PCl; at 25.55 "C is added to 1.00 x 10g of water at 25.55 "C in a 'coffee-cup' calorimeter, the temperature of the resulting solution increases to 32.00 "C. If the specific heat capacity of the solution is 4.184 J/"Cg, and the heat capacity of the Styrofoam cup is negligible, calculate the molar heat of solution of PC13 in water.
