In an experiment, 11.6g of a salt was dissolved in 100.0ml of water contained in the above calorimeter, all at an initial tmperature of 24.5 degrees Celsius. After dissolution was complete, the temperatur was 31.8C. The specific heat of the solution is 3.63J/gxC and the molecular mass of the salt is 153.5 g/mol. Assume there is no heat loss to the surroundings.

A) Calculate the heat gained by the soution

B) Calculate the heat gained by the calorimeter

C) Calculate the total ehat gained by the system.

D) Calculate the heat of solution (delta H)of the salt in J/mol.
