How many times faster will helium gas effuse compared to neon gas?
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
