temperature change?

Question

3.09474 KJ of energy is gained/lost by 236.0 ml of water containing 4.08 g of dissolved MgSO4, according to the equation,

MgSO4 → Mg2+(aq) + SO42−(aq).

The change in enthalpy must be −91.3 kJ/mol. What is the change in temperature ( oC ) for the above process assuming no heat is lost or gained by the surroundings ?
