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

A

CO

B

`CO_(2)`

C

`H_(2)`

D

NO

Text Solution

Verified by Experts

The correct Answer is:
A
If same volume is occupied by the gas, the no. of molecules are same, so no. of moles are same.
1mole of `N_(2)` gas `= 2 xx 14 = 28g`
1 mole of CO gas = 12 + 16 = 28 g`
