Calculate the number of oxygen atoms in 29.34 g of sodium sulfate, Na₂SO₄.

Question

Quizplus · Accepted Answer

The molecular formula for sodium sulfate is Na2SO4, which contains 4 oxygen atoms per molecule. The molar mass of Na2SO4 is approximately 142 g/mol. Therefore, 29.34 g of Na2SO4 is equivalent to 29.34 g / 142 g/mol = 0.2066 mol. Since there are 4 oxygen atoms per Na2SO4 molecule, the total number of oxygen atoms is 0.2066 mol * 4 * Avogadro's number (6.022 × 10^23 atoms/mol) = 4.976 × 10^23 O atoms.
