this can be solve using the grahams law, which states that the rate of diffusion of the gas is inversely proportional the square root of the molar mass of the gas. meaning the gas with smaller molar mass is the fastest to diffuse
molar mass of the following F2 = 38 g/mol CO2 = 44 g/mol He = 4 g/mol SO2 = 64 g/mol NO = 30 g/mol NH3 = 17 g/mol
