`350 cm^3` of `CH4 ` and `175cm^3` of an unknown gas 'A' diffused in the same time under similar conditions. The molecular mass of gas A is 

A

32

B

64

C

30

D

71

Text Solution

Verified by Experts

`((DeltaV_1)/(t_1))/((DeltaV_2)/(t_2)) = sqrt((M_2)/(M_1))`
` (350)/(175) = sqrt(x/16) implies x = 2^2 xx 16 = 64`.
