5. 21 g of mgso₄ is placed into 100. 0 ml of water. The water's temperature increases by 6. 70°c. Calculate ∆h, in kj/mol, for the dissolution of mgso₄. (the specific heat of water is 4. 184 j/g･°c and the density of the water is 1. 00 g/ml). You can assume that the specific heat of the solution is the same as that of water
