WebThe number of moles of potassium chlorate is 0.715 mol. Step 2: Calculation of the number of moles of oxygen We can calculate the number of moles of oxygen with that of potassium chlorate. 2 moles of potassium chlorate gives 3 moles of oxygen. So, 0.715 mole of potassium chlorate gives 3 2 × 0. 715 mol = 1.0725 mol of oxygen gas.
