Question
When a 5.12-g sample of solid sodium nitrate dissolves in 58.0 g of water in a coffee-cup calorimeter (see above figure) the temperature falls from 21.00 oC to 16.05 oC. Calculate H in kJ/mol NaNO3 for the solution process.
NaNO3(s) Na+(aq) + NO3-(aq)
The specific heat of water is 4.18 J/g-K.
Hsolution = kJ/mol NaNO3.
