The time taken for the same volume of oxygen to effuse is 40 s while gas Y takes 20 s under the same conditions. The molecular weight of Y is :

Answer:

Solution:

For the same volume, rate is inversely proportional to time: r(Y)/r( $O_{2}$ ) = 40/20 = 2.

r(Y)/r( $O_{2}$ ) = $M (O_{2}$ / $M$ (Y)) = 2, so 32/ $M$ (Y) = 4.

$M$ (Y) = 8.

Answer: (D).
