Juan performed a calorimetry experiment to determine ?H for the following reaction:
KOH (s) -> K+ (aq) + OH- (aq)
His calorimeter contained 64.0 g of water at an initial temperature of 20.7°C. When he added 1.65 g of KOH (s) to the calorimeter, the temperature rose to 26.9°C. What value of ?H can Juan obtain from his data?
