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
Mass ratio of `O_(2) : N_(2)` is 1 : 4, Mole ratio of `O_(2) : N_(2)` is : `(1)/(32) : (4)/(28)`
Ratio of molecules of `O_(2) : N_(2)` is same as molar ratio i.e. 7 : 32.
