The molar mass of the hydrated sodium sulfate is 322.1 g/mole. What is the formula of the hydrate salt?

Na₂SO₄·10H₂O.

Explanation:

Hello.

In this case, since the anhydrous sodium sulfate is:

Whose molar mass is:

But the total hydrate's molar mass is 322.1 g/mol, we can compute the mass of water:

Thus, the molecules of water are found by diving the total mass of water by the mass of one mole of water:

It means, that the formula is Na₂SO₄·10H₂O.
