Answer :
Final answer:
When 100.0 grams of potassium chlorate is heated, the mass of oxygen produced is 48.0 grams.
Explanation:
To find the mass of oxygen produced when 100.0 grams of potassium chlorate is heated, we need to use the balanced chemical equation for the decomposition of potassium chlorate (KClO3): 2 KClO3 → 2 KCl + 3 O2
From the equation, we can see that for every 2 moles of KClO3 that decompose, 3 moles of O2 are produced.
Using the molar mass of KClO3 and O2, we can calculate the mass of O2 produced:
100.0 g KClO3 x (3 moles O2 / 2 moles KClO3) x (32.00 g O2 / 1 mole O2) = 48.0 g O2
Therefore, the mass of oxygen produced when 100.0 grams of potassium chlorate is heated is 48.0 grams.
