Pоtаssium chlоrаte decоmposes аccording to the balanced equation: 2 KClO₃(s) → 2 KCl(s) + 3 O₂(g) A sample containing 12.25 g KClO₃ decomposes completely. What volume of O₂ gas is produced at STP? Use a molar mass of 122.55 g/mol for KClO₃ and 22.4 L/mol for a gas at STP. Enter a numerical answer to three significant figures.
