The data given in the Excel file for this part are in columns. We use only the last number in each column (not an average) since this last number represents a "Constant Mass" after heating. Calculate the following: 1) Mass of Hydrate sample 2) Mass of Water driven off by the heating 3) Mass of the Anhydrous MgSO4 4) % water in the hydrate (This is your % Water experimental value) 5) Moles water in the sample (use 18.015 g/mol for water) 6) Moles MgSO4 in the sample 7) Ratio of moles H₂O to moles MgSO4 8) Formula of the hydrate (round Ratio to a whole number) 9) % Water from determined formula (Use this as your % Water accepted value) 10) % Error for the % water value
