Step-by-step explanation:
Look up the molar masses of each component element:
• Mg : 24.305 g/mol
• S : 32.06 g/mol
• O : 15.999 g/mol
• H : 1.008 g/mol
Then MgSO₄•7H₂O has a total molar mass of about 246.466 g/mol. 7H₂O has a total molar mass of about 126.105 g/mol, so it makes up about 0.5117 or 51.17% of the total mass.
Now, 0.01132 mol of MgSO₄•7H₂O has a mass of
(0.01132 mol MgSO₄•7H₂O) × (246.466 g/mol) ≈ 2.79 g
which means water makes up about 1.428 g (i.e. 51.17% of the mass of MgSO₄•7H₂O).
