if 14.3 g of table salt (nacl) is put into 236.0 g of water at 25 degrees celsius, the water cools down when the salt dissolves such that the final temperature is 24.16 degrees celsius. What is the delta H reaction (Kj/mol)? (MMNaCl= 58.44 g/mol)

answer is 3.60 kJ/mol, I'm just not sure how to get that
