Subjective Type

A vessel contains X number of molecules of hydrogen gas at a certain temperature and pressure. How many molecules of nitrogen gas would be present in the same vessel under the same conditions of temperature and pressure?

Solution

According to Avogadro's law,

"Under same condition of temperature and pressure, equal volumes of all gases contains the same no. of molecules".

At the same condition of temperature and pressure, the number of molecules of both the gases will be same.

Thus, there are X number of molecules of nitrogen gas also present.
