You mix 5.32 g of solid magnesium sulfate with 105.24 g of water inside a calorimeter. As the magnesium sulfate dissolves, the temperature of the solution rises from 24.5°C to 30.1°C. Calculate the amount of energy in kJ that was transferred into the surroundings through heating. Assume that the specific heat capacity of the solution is 4.18 J/g·°C.

q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
Since this is an exothermic reaction, the prof MAY want a negative sign on it; one never knows. I wouldn't use one since if heat is being transferred into the surroundings it MUST have been exothermic.
