Question:

What mass of potassium chlorate must be heated to give 120 cm{eq}^3 {/eq} of oxygen according to the following equation?

{eq}2KClO_3(s) \to 2KCl(s) + 3O_2(g) {/eq}

Ideal Gases Molar Volume

Assuming that a gas behaves ideally at standard temperature and pressure (STP), the approximate volume of the gas is 22.4 Liters per mole. This is derived from the ideal gas law.
