To calculate the rate of diffusion of carbon dioxide CO2 gas in air, we can use Graham's law of diffusion. Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass. Mathematically, it can be represented as:Rate1 / Rate2 = Molar Mass2 / Molar Mass1 In this case, we want to find the rate of diffusion of CO2 Rate1 in air. We are given the molar mass of CO2 44 g/mol . We also need the molar mass of air and the rate of diffusion of air Rate2 .Air is primarily composed of nitrogen N2, 78% and oxygen O2, 21% , with trace amounts of other gases. We can approximate the molar mass of air using a weighted average of the molar masses of nitrogen and oxygen:Molar Mass of air 0.78 28 g/mol + 0.21 32 g/mol 28.84 g/molNow, we need the rate of diffusion of air Rate2 . However, this information is not provided in the problem. Without the rate of diffusion of air, we cannot directly calculate the rate of diffusion of CO2 using Graham's law.If you can provide the rate of diffusion of air or any other reference gas, we can then calculate the rate of diffusion of CO2 using Graham's law.
