The following gases are at STP. Which one will diffuse the fastest? F2, CO2, He, SO2, NO, NH3

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
