Web8 apr. 2024 · Molar mass of the potassium chlorate is 122.5 g/mol. Substitute 122.5 g/mol for molar mass and 1.6 mol for moles of potassium chlorate. ⇒ 1 .6 mol = Mass 122.5 g/mol ⇒ Mass of KCl O 3 = 1 .6 mol × 122.5 g/mol ⇒ Mass of KCl O 3 = 1 96 g So, 1 96 g grams of KCl O 3 will give 2.4 mole O 2. Web1st step. All steps. Final answer. Step 1/3. Potassium chlorate decomposes to form potassium chloride and oxygen. The chemical reaction is 2 KClO A 3 A ( s) 2 KCl A ( s) + 3 O A 2 A ( g). 244 grams of potassium chlorate is decomposed, and 148 grams of potassium chloride is formed. The amount of oxygen formed in grams is to be calculated. dialyvite used for
