When 10.0 g of potassium hydroxide (KOH) is dissolved in 100.0 g of water, the temperature rises from 25.18 °C to 47.53 °C. What is the heat of solution of KOH in units of joules/gram? The total mass of the solution is 110.0 g (100.0 g H2O + 10.0 g KOH = 110.0 g) and its specific heat capacity is 4.18 J/(g·K).
