Question

Your starting mixture contains both KCl and KClO3. Suppose that your starting mixture weighed 2.040 grams total, and suppose that you dertermined during your reaction that you produced 0.0072 mols of O2. The balanced equation for this reaction tells you that you produce 2 mols of O2 for every 3 mols of KClO3 you use. Based on this information, what percentage of KClO3 in the original mixture? (information that may or may not be helpful: Molar mass of KClO3 is 122.5g/mol, molar mass of KCl is 74.5 g/mol, molar mass of O2 is 32.0 g/mol)
