Volumes of `N_(2) and O_(2)` in any gas mixture are 80% and 20T respectively. Determine the average vapour density of the gas mixture.

Text Solution

Verified by Experts

Vapour density of `N_(2)=(M_(N_(2)))/(2)=(28)/(2)=14` and
vapour density of `O_(2)=(M_(O_(2)))/(2)=(32)/(2)=16`
`therefore`Average density of the gas mixture
`=(80xx"vapour density of "N_(2)+20xx" vapour density of "O_(2))/(100)`
`=(80xx14+20xx16)/(100)=14.4`
