`10dm^(3)` of `N_(2)` gas and 10 `dm^(3)` of gas X at the same temperature contain the same number of molecules The gas X is

A

CO

B

`CO_(2)`

C

`H_(2)`

D

`NO`

Text Solution

Verified by Experts

The correct Answer is:
A
No. of moles of `N_(2)` and X should be equal. This can be so if X has same molecular mass as `N_(2)` viz. CO.
