Samples of the gases `O_(2) ,N_(2), CO_(2) and CO` under the same conditions of temperature and pressure contain the same number of molecules represented by X. The molecules of oxygen `(O_(2))` occupy V litres and have a mass of 8 g. Under the same conditions of temperature and pressure, answer the following questions:
What is the volume occupied by
X moelcules of `N_(2)`

Explanation

Avogdaro.s law states that same conditions of temperature and pressure, equal volumes of gases contain number of molecules thus
The volume occupied by X molecules of `N_(2)` is the same as the volume occupied by X moelcules of `O_(2)`. Therefore, the volume occupied by X molecules of `N_(2)` is alos V lites.
