Complete Question

To make use of an ionic hydrate for storing solar energy, you place 422.0 kg of sodium sulfate decahydrate on your house roof. Assuming complete reaction and 100% efficiency of heat transfer, how much heat (in kJ) is released to your house at night? Note that sodium sulfate decahydrate will transfer 354 kJ/mol.

The amount of energy released is

Explanation:

Number of moles is mathematically represented as

substituting for mass of sodium sulfate decahydrate(), (This value is a constant )for the molar mass of sodium sulfate decahydrate

From the question we are told that

            1 mole of sodium sulfate decahydrate generates of energy

         So  1309.7 mole would generate  x

Now stating the relation mathematically

                 1 mol → 354KJ

                 1309.7 mol → x

=>
