What is the final temperature in degree C when 8.70 grams of Lithium sulfate are dissolved in 60.00 grams of H2O?

Report the temperature to the tenths of a degree.

Heat of solution for Lithium sulfate is - 29.8 kJ / mole. (negative 29.8)

The initial temperature of the water and the Lithium sulfate are both 25.0 oC.

Assume the specific heat of the solution is the same as the specific heat of pure water.

Assume no heat is lost or gained from the surroundings.
