Reference no: EM13285155

When a 8.26-g sample of gaseous hydrogen bromide dissolves in 36.2 g of water in a coffee-cup calorimeter (see above figure) the temperature rises from 25.00 oC to 71.53 oC. Calculate H in kJ/mol HBr for the solution process.

HBr(g) -> H+(aq) + Br-(aq)

The specific heat of water is 4.18 J/g-K.

delta Hsolution = ? kJ/mol HBr.
