A gaseous mixture contains H(2) , and N(...

A gaseous mixture contains `H_(2)` , and `N_(2)` , in the ratio of 1:4 by weight, the ratio of the molecules is

A

`7:2`

B

`1:8`

C

`2:7`

D

`1:4`

Text Solution

Verified by Experts

The correct Answer is:
A
Molecular masses of `H_(2)` , and `N_(2)` = 2 and 14
Ratio of molar masses = 2:14 or 1:7
Ratio of `H_(2)` , and `N_(2)` , in the mixture by weight = 1:4
Ratio of the molecules = 7:2
