Question

The decomposition of potassium chlorate (KClO3) is used as a source of oxygen in the laboratory. How much potassium chlorate is needed to produce 10.2 mol of oxygen? Answer in units of mol

Answer 1

15.3 mol

Answer 2

Laila is El wrongo! Used the factor upside down to get 15.3.

2KClO3 ==> 2KCl + 3O2
mols KClO3 = mols O2 x (2 mols KClO3/3 mols O2) = 10.2 x (2/3) = ?

Answer 3

2KClO3 ==> 2KCl + 3O2
mols KClO3 = mols O2 x (2 mols KClO3/3 mols O2) = 10.2 x (2/3) = ?
