If 200 g of CaCO₃ decomposes to form CO₂ gas and CaO solid, how many liters of CO₂ will form?

Question

Quizplus · Accepted Answer

The correct formula for the decomposition reaction is CaCO3 → CO2 + CaO. Given that 1 mole of CaCO3 (100 g/mol) produces 1 mole of CO2, 200 g of CaCO3 will produce 2 moles of CO2. At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 liters. Therefore, 2 moles of CO2 will occupy 44.8 liters.
