A gaseous mixture contains oxygen and nitrogen in the ratio of `1 : 4` by weight therefore the ratio of their number of molecules is

A

`1:8`

B

`3:16`

C

`1:4`

D

`7:32`

Text Solution

Verified by Experts

The correct Answer is:

Moles of `O_(2) = (w)/(32)`
Moles of `N_(2) = (4w)/(28)`
`n_(O_(2)) : n_(N_(2)) = 7:32`
