The mass (in grams) of MgSO₄ That should be used is 1.26 g

How to determine the mass of MgSO₄

We'll begin by writing the balanced equation for the reaction. This is given below:

MgSO₄ + 2HCl —> MgCl₂ + H₂SO₄

  • Molar mass of MgSO₄ = 24 + 32 + (16 × 4) = 120 g/mol
  • Mass of MgSO₄ from the balanced equation = 1 × 120 = 120 g
  • Molar mass of MgCl₂ = 24 + (35.5 × 2) = 95 g/mol
  • Mass of MgCl₂ from the balanced equation = 1 × 95 = 95 g

Finally, we shall determine the mass of MgSO₄ needed for the reaction as follow:

From the balanced equation above,

95 g of MgCl₂ were produced from 120 g of MgSO₄

Therefore,

1 g of MgCl₂ will be produce from = (1 × 120) / 95 = 1.26 g of MgSO₄

Thus, the mass of MgSO₄ needed is 1.26 g
