a 7.45g sample of solid LiOH is completely dissolved in 12.00g of water at 23.25degree C contained in a calorimeter with a heat capacity of 11.7J/Celcius. The specific heat capacity of the solution produced was 4.20J/g*Celcius, and final temp reached was 34.91 degrees c. How much heat was produced by the dissolution?
