A gas mixture contains `50%` helium and `50%` methane by volume. What is the percent by weight of methane in the mixture.

A

0.1997

B

0.2005

C

0.5

D

0.8003

Text Solution

Verified by Experts

The correct Answer is:
D
Equal volumes contain equal no. of moles
`therefore` Molar mass = `1:1`
Ratio by weight `=4:16 = 1:4`
`therefore CH_(4)` present by weight
`=4/6 xx 100 = 80%`
