To convert volumes of CO2 to grams per Litre, follow these steps: 1. Identify the molar volume of CO2 at standard temperature and pressure (STP), which is 22.4 L. 2. Calculate the molar mass of CO2 (about 44 g/mol). 3. Use the formula: grams/L = (volume of CO2 in L) × (molar mass of CO2 / molar volume at STP). For example, 1 L of CO2 = 1 × (44/22.4) = 1.96 g of CO2 per Litre.

FAQs & Answers

  1. What is the molar volume of a gas at STP? The molar volume of a gas at standard temperature and pressure (STP) is 22.4 L.
  2. How do I calculate the molar mass of CO2? The molar mass of CO2 is calculated by adding the atomic masses of its constituents: carbon (12 g/mol) and two oxygen atoms (16 g/mol each), resulting in 44 g/mol.
  3. What is STP in chemistry? STP stands for standard temperature and pressure, defined as 0 degrees Celsius (273.15 K) and 1 atmosphere (atm) of pressure.
  4. Why is it important to convert gas volumes to grams? Converting gas volumes to grams is important for precise scientific calculations, reactions, and stoichiometry in chemistry.
