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

A

`1:4`

B

`1:8`

C

`7:32`

D

`3:16`

Text Solution

Verified by Experts

The correct Answer is:
C
Moles of molecules of `O_(2). N_(2) = (1)/(32) : (4)/(28)`
`= (1)/(32) : (1)/(7) = (7)/(32) : 1 = 7:2`
