Question

Two gases A and B have same volumes diffuses through a porous pot in 10 and 5 seconds respectively if the molar mass of gas a if 40 then find the molar mass of B......

Answer 1

hey mate⭐️
I think it is 20
thanks❤️
hope it helps

Answer 2

Answer:

10

Explanation:

Given , both gases have same volume so let it be V . Time taken by gas A is 10sec and by B is 5sec and molar mass of A is 40.

R1/R2 = √M2/√M1

And we also know R1/R2=V1T2/V2T1

√M2/40 = V×5/V×10

M2/40 = 1/4

M2=10

Therefore mass of gas B is 10
