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.
I answered this for you earlier.
thanks bobpursley. drbob222 you answered the first part but i also needed helpp on the second
