In an experiment, zinc chlorate decomposed according to the following chemical equation:

Zn(ClO3)2 → ZnCl2 + 3O2

(Molar mass of Zn(ClO3)2 = 232.29 g/mol; ZnCl2 = 136.286 g/mol; O2 = 31.998 g/mol)

If the mass of zinc chlorate was 150 grams, which of the following calculations can be used to determine the mass of oxygen gas formed? (4 points)

(150 × 1 × 232.29) ÷ (31.998 × 3) grams

(150 × 3 × 232.29) ÷ (31.998 × 1) grams

(150 × 1 × 31.998) ÷ (232.29 × 3) grams

(150 × 3 × 31.998) ÷ (232.29 × 1) grams
