How many times faster will helium gas effuse compared to neon gas?
How many times faster will helium gas effuse compared to neon gas?
Solutions
Expert Solution
He gas Ne gas
atomic mass of He (MHe) = 4g/mole atomic mass of Ne ( MNe) = 20g/mole
rate of effuse of He r He = rate of effuse of Ne r Ne
r He/r Ne = 
MNe/MHe
r He/r Ne = 20/4
r He/r Ne = 2.24
r He = 2.24 r Ne
2.24 times faster will helium gas effuse compared to neon gas
