192 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.
