    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

    so the fastest is He
