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 kcl produced was 180 grams, which of the following calculations can be used to determine the mass of potassium chlorate decomposed? (180 × 2 × 74.55) ÷ (122.5 × 2) grams (180 × 3 × 74.55) ÷ (122.5 × 2) grams (180 × 2 × 122.5) ÷ (74.55 × 2) grams (180 × 3 × 122.5) ÷ (74.55 × 2) grams
