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?
A. (240 × 2 × 31.998) ÷ (122.5 × 3) grams
B. (240 × 3 × 31.998) ÷ (122.5 × 2) grams
C. (240 × 2 × 122.5) ÷ (31.998 × 3) grams
D. (240 × 3 × 122.5) ÷ (31.998 × 2) grams
