Answer:

50.25 g of sulphur, S.

Step-by-step explanation:

Mass of Na₂SO₄ = 223 g

Mass of sulphur =?

Next we shall determine the molar mass of Na₂SO₄. This can be obtained as follow:

Molar mass of Na₂SO₄ = (23×2) + 32 + (16×4)

= 46 + 32 +64

= 142 g/mol

Mass of S in 142 g of Na₂SO₄ = 32 g

Finally, we shall determine the mass of S in 223 g of Na₂SO₄. This can be obtained as follow:

142 g of Na₂SO₄ contains 32 g of S.

Therefore, 223 g of Na₂SO₄ will contain = (223 × 32) / 142 = 50.25 g of S.

Thus, 223 g of sodium sulfate, Na₂SO₄ contains 50.25 g of sulphur, S.
