Question

When 5.12g of NaOH were dissolved in 51.55g water in a calorimeter at 24.5C, the temperature of the solution went up to 49.8Ca) calculate qh20b) find delta H for the reaction as it occurred in the calorimeterc) find delta H for the solution of 1g NaOH in waterd) find delta H for the solution of 1 mole NaOH in watere) Given the following heats of formation, delta Hf, in kJ per mole, as obtained from a table of delta Hf data, calculate delta H for the reaction NaOH(s)---->Na+(aq)+OH-(aq). Compare your answer with the result you obtained for part d. NaOH(s), -425.6; Na+(aq), -240.1; OH-, -230.0
