Gas A taken in a closed rigid container is allowed to decompose partially according to the reaction
`A(g)rarr2B(g)+3C(g)`
The gaseous mixture formed effuses 1.5 times faster than a gas having molecular weight 105 under similar conditions. Find the mole fraction of C in the gaseous mixture formed
Given : Mol. wt. of `A = 140`
Mol. wt. of `B = 64 `
Mol. wt. of `C = 4`
Write your answer by multiplying with 10.
