The ratio of masses of oxygen and nitrogen in a particular gaseous mixture `1:4`. The ratio of number of their molecule is :

A

`1:4`

B

`7:32`

C

`1:8`

D

`3:16`

Text Solution

Verified by Experts

The correct Answer is:
B
Number of moles of `O_(2)=w/32`
Number ot moles of `N_(2)=(4w)/28=w/7`
`therefore` Ratio `=w/32:w/7=7:32`
