Question
A compound contains 32.43% sodium, 22.52% sulfur, and 45.05% oxygen by mass. What is its empirical formula? (Atomic masses: Na = 23, S = 32, O = 16)
Explanation
For 100 g: Na = 32.43 g, S = 22.52 g, O = 45.05 g. Moles: Na ≈ 1.41, S ≈ 0.704, O ≈ 2.82. Ratio = 2 : 1 : 4; empirical formula = Na₂SO₄.
