A 7.45 g sample of solid LiOH is completely dissolved in 120.00 g of water at 23.25°C contained in a calorimeter with a heat capacity of 11.7 J/°C. The specific heat capacity of the solution produced was 4.20 J/g•°C, and final temperature reached was 34.91°C. How much heat was produced by the dissolution?
