Oxygen gas can be produced by the thermal decomposition of potassium chlorate, KClO3\text{KClO}_3KClO3.
2KClO3→2KCl+3O2 2\text{KClO}_3 \rightarrow 2\text{KCl} + 3\text{O}_2 2KClO3→2KCl+3O2Calculate the maximum volume, in cm3\text{cm}^3cm3, of oxygen produced from 49 g of potassium chlorate.
(relative formula mass: KClO3=122.5\text{KClO}_3 = 122.5KClO3=122.5; 1 mol of gas occupies 24 dm3 in the conditions used)
