Discover how to calculate the volume of 16g of CO2 using the ideal gas law at standard temperature and pressure.
54 views
To find the volume of 16g of CO2, utilize the ideal gas law: PV = nRT. At standard temperature and pressure (STP), 1 mole of gas = 22.4 liters. CO2 has a molar mass of 44g/mol. Thus, 16g CO2 is 16/44 ≈ 0.36 moles. Volume = 0.36 moles x 22.4 L/mol ≈ 8.1 liters. Therefore, 16g of CO2 equates to approximately 8.1 liters.
FAQs & Answers
- What is the ideal gas law? The ideal gas law is a relation between pressure, volume, temperature, and number of moles of an ideal gas, expressed as PV=nRT.
- How do you calculate the number of moles in a gas? To calculate the number of moles, divide the mass of the substance in grams by its molar mass.
- What volume does one mole of gas occupy at STP? At standard temperature and pressure (STP), one mole of gas occupies 22.4 liters.
