Answer:

See explanation

Explanation:

1) From the reaction equation;

2 moles of KClO3 yields 2 moles of KCl

Hence,

4 moles of KClO3 yields 4 * 2/2 = 4 moles of KCl

2) Given that from the reaction equation, we have;

Burning 3 * 6.02 * 10^23 molecules of oxygen yields 2 * 22.4 L of CO2

Hence,

7 * 10^25 molecules of oxygen yields 7 * 10^25 * 2 * 22.4 / 3 * 6.02 * 10^23

= 313.6 * 10^25/18.06 * 10^23

= 17.36 * 10^2

= 1736 L
