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
