26.5 g of Fe₂(SO₄)₃
Explanation:
We have the following chemical reaction:
2 FePO₄ + 3 Na₂SO₄ → Fe₂(SO₄)₃ + 2 Na₃PO₄
number of moles = mass / molecular wight
number of moles of FePO₄ = 20 / 151 = 0.1325 moles
Taking in account the chemical reaction we devise the following reasoning:
if 2 moles of FePO₄ produces 1 mole of Fe₂(SO₄)₃
then 0.1325 moles of FePO₄ produces X moles of Fe₂(SO₄)₃
X = (0.1325 × 1) / 2 = 0.06625 moles of Fe₂(SO₄)₃
mass = number of moles × molecular wight
mass of Fe₂(SO₄)₃ = 0.06625 × 400 = 26.5 g

I hope this helped ;)))
