In an experiment, potassium chlorate decomposed according to the following chemical equation.
kcio3 β†’ kci + o2
(molar mass of kcio, - 1225 g/mol kci = 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 x 2 x 74.55) + (122.5 x 2) grams
(180 x 3 x 74.55) + (122.5 x 2) grams
o (180 * 2 * 122.5) + (74.55 * 2) grams
1902
122.5) + (74 55 x 2) grams
