To calculate the volume of CO2 gas produced in a reaction, use the formula: Volume = Number of Moles × Molar Volume. The molar volume of a gas at Standard Temperature and Pressure (STP) is 22.4 liters per mole. For instance, if you have 2 moles of CO2: Volume = 2 moles × 22.4 L/mole = 44.8 liters. Ensure you’re working under STP conditions for this calculation to be accurate.

FAQs & Answers

  1. What is the molar volume of CO2 at STP? The molar volume of CO2 at Standard Temperature and Pressure (STP) is 22.4 liters per mole.
  2. How do I convert moles of CO2 to volume? To convert moles of CO2 to volume, multiply the number of moles by the molar volume at STP, which is 22.4 L/mole.
