As per Avogadro’s law under constant temperature and pressure there will be same amount of moles present in the same volume of gas. If the gas increases, the amount of moles also increases. In other words we can say that the volume of gas(V) is directly proportional to the number of moles present (n). So we can say,
The amount of moles is called Avogadro’s constant.
I am not 100% sure this is write but I did my best this is still kinda hard for me. I just did this a few years ago and i struggled with it but I have been doing better since then.
