The problem statement, all variables and given/known data
When 5.00 g of NaOH(s) are added to 100 g of water using a calorimeter (with Cp = 493.24 J/K), the temperature rises from 25.0 to 37.5 C. Calculate the molar heat of solution.
NaOH(s)--->Na(aq)+OH(aq)
Assume that the specific heat capacity of water is 4.18 J/gK and that of the NaOH(aq) solution is the same.
