. When a 28.7 g sample of KI dissolves in 60.0 g of water in a calorimeter, the temperature drops from 27.2oC to 13.2 oC . Calculate ΔH for the process.
Chemistry Science -
q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
That is dH for the process BUT you probably want per mol KI. q/mol KI = ?
