In an experiment, potassium chlorate decomposed according to the following chemical equation. kclo3 → kcl + o2 (molar mass of kclo3 = 122.5 g/mol; kcl = 74.55 g/mol; o2 = 31.998 g/mol) if the mass of potassium chlorate was 240 grams, which of the following calculations can be used to determine the mass of oxygen gas formed? (240 × 2 × 31.998) ÷ (122.5 × 3) grams (240 × 3 × 31.998) ÷ (122.5 × 2) grams (240 × 2 × 122.5) ÷ (31.998 × 3) grams (240 × 3 × 122.5) ÷ (31.998 × 2) grams
