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

A

`3:16`

B

`1:4`

C

`7:32`

D

`1:8`

Text Solution

Verified by Experts

The correct Answer is:
C
Ratio of masses of `O_(2)` and `N_(2)=1:4`
`therefore` Ratio of moles of `O_(2)` and `N_(2) =1/32 : 4/28`
`=7:32`
`therefore` Ratio of molecules of `O_(2)` and `N_(2)= 7:32`
