This numerical is based on the Grahams law.
Here the case is of effusion.
Use
R= PA/root over 2m
Here A is constant
From ideal gas eqn.
P=nRT/V
R, T are constant.
P=n/V
You can calculate the no. Of moles.
Now the formula becomes
R1/R2 = n1/v1 divided by n2/v2 × root over M2/M1
Hope you get your answer.
