The molecular formula for MgSO4 (Magnesium sulfate) seems to be incorrectly written as "MgSO₄". The molar mass of MgSO4 is approximately 120.37 g/mol. To find the number of moles in 1.64g of MgSO4, use the formula: moles = mass (g) / molar mass (g/mol). Thus, moles = 1.64g / 120.37g/mol ≈ 0.0136 moles.
