Question

A student mixes 1.00 L of 1.00 -M Ca(NO3)2 solution at 25.0 C with 1.00 L of 1.00 -M Na2SO4 solution at 25.0C in a calorimeter, solid CaSO4 forms, and the temperature of the mixture decreases to 22.9 C. Assuming that the calorimeter absorbs only a negligible quantity of heat, the specific heat capacity of the solution is 4.18 J/°C·g, and the density of the final solution is 1.0 g/mL, calculate the enthalpy change per mole of CaSO4 formed.
