You are given 1.000 grams of hydrated Magnesium Sulfate (MgSO4*XH20). You place it into a crucible and heat it up past 100 C so that the water evaporates from the hydrated salt. Once you are done, the mass of the dry anhydrous Magnesium Sulfate is 0.488 grams.

How many molecules of water are attached to each atom of Magnesium?

There would be seven mols of water per every mol of MgSO4.
