WebCalculate the formula of the hydrated compound. Solution: 1) Assume 100. g of the hydrate is present. CuSO4---> 74.7 g H2O ---> 25.3 g 2) Change to moles: CuSO4---> 74.7 g / 159.607 g/mol = 0.468 mol H2O ---> 25.3 g / 18.0 g/mol = 1.406 mol 3) Divide by the smallest: CuSO4---> 0.468 mol / 0.468 mol = 1 Web17 jun. 2024 · The number of waters of hydration is given by the number of moles of water present for every 1 mole of anhydrous salt. In your case, you know that. 0.04004 moles MgSO4 → 0.2798 moles H2O. This means that 1 mole of magnesium sulfate will have. 1moles MgSO4 ⋅ 0.2798 moles H2O 0.04004moles MgSO4 = 6.988 ≈ 7.
