When 19 g KOH is dissolved in 97.1 g of water in a coffee-cup calorimeter, the temperature rises from 18.1 °C to 33.81 °C. What is the enthalpy change per gram (in J/g) of KOH dissolved in the water? Assume that the solution has a specific heat capacity of 4.18 J/g×K. Water has a density of 1.00 g/ml. Be sure to enter the correct sign (+/-). Enter to 1 decimal place.
