Question

A student adds 15.0 g of LiBr(s) to an insulated container holding 150.0 g of water at 22.0°C. After
the LiBr(s) has completely dissolved, the final temperature of the solution is 34.2°C.
Calculate the amount of heat, in kJ, that was absorbed by the solution during the dissolution process.
(Assume that the solution has a specific heat of 4.18 J/(g. °C).)
Write your answer using three significant figures.
