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? (4 points)
Group of answer choices
(240 x 2 x 31.998) ÷ (122.5 x 3) grams
(240 x 2 x 122.5) ÷ (31.998 x 3) grams
(240 x 3 x 122.5) ÷ (31.998 x 2) grams
(240 x 3 x 31.998) ÷ (122.5 x 2) grams
