According to Avogadro's Hypothesis, how much volume does one mole of gas occupy at STP?

According to Avogadro's Hypothesis, one mole of an ideal gas occupies a volume of 22.4 liters at standard temperature and pressure (STP), which is defined as a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere. This concept arises from the observation that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules, and it is fundamental to understanding the relationships between moles, volume, and gas behavior in chemistry.

This volume of 22.4 liters is a critical value used in stoichiometric calculations involving gases and is integral in the ideal gas law (PV = nRT), where it helps relate the amount of substance in moles to the corresponding volume in liters under defined conditions.
