Krypton gas is four times denser than neon gas at the same temperature and pressure.

Which gas is predicted to effuse faster?

i got neon which is correct

but How much faster? how many times? i don't know how to get htis

    lighter molecules effuse faster.

    Graham's law: Rate of effusion is inverely proportional to the square root of molecular mass.

    So neon effuses faster. Go to the head of your class.

    how much faster: rateneon=rateKr*sqrt(83.7/20.1) or about twice as fast.
