Avagadro's Law and The Combined Gas Law

So today we will discuss Avagadro's Law, which is a law that involves moles, so the first thing you need to know is that at STP, which is 1 atm and 0 degrees Celsius, there are 22.4 Liters of gas in one mole. Our next law will go over when the gas is not at STP. Avagadro's Law says that if there is a constant temperature and pressure, it does not have to be at STP, the volume is directly proportional to the number of moles. If you don't understand then go HERE. The equation also can look like this

Where V=Volume, n=amount in moles

There is also the combined gas law. It is really just an equation that shows the relationship between pressure, volume, and temperature; however it only applies when the amount of gas is constant. The equation looks something like this:

And that is all, thanks for reading.
