Molar volume
Molar volume Definition: Molar volume is the volume of one mole of a substance. The volume occupied in the form of a solid, liquid, or gas by one mole of a substance is molar-volume, the volume occupied by a mole of a substance at STP.

When asked to define Molar volume it can be defined as the volume occupied by a mole of a substance at STP. Standard Molar volume is the volume occupied by one mole of gas, it can be any gas, at Standard Temperature and Pressure. The Value for Standard Temperature in Celsius is 00C or in Kelvin is 273K. The Standard Pressure is 1 atmosphere or 760 mm Hg. One mole of any gas at Standard Temperature and Pressure occupies 22.4 liters of Volume.
1 mole of any gas at STP occupies 22.4 liters of volume. This information, helps us to find the volume occupied by any number of moles (or grams) of gas. Conversely, the number of moles present in any volume of gas at STP can also be determined, and if the identity of the gas is known, this number of moles can be converted to a mass.
Standard molar-volume can also be used to determine the density of gases at STP. The density at STP is given by mass of one mole / 22.4 liters. Avagadro’s law states that at a given temperature and pressure a given volume of any gas contains the same number of molecules. At STP one mole of gas occupies 22.414 liters. The molar volume of Gas is the volume occupied by this gas.
For calculating Molar volume of a gas we use the equation pv = nrt, where p = pressure , v = volume, n=moles, r is a constant (8.413372) and t is the temperature.
You can also use pv/t = pv/t where one side is stp (standard temperature and pressure) and the other side is your information with one variable left over which can be found out. . If the molar mass can be determined, from the chemical formula, for instance, then the density can be calculated.
Having problem with Calculating Empirical Formula keep reading my upcoming posts, i will try to help you.
Using PV = nRT, you the molar-volume can be found. . V is the unknown and n = 1.00 mol. Set P and T to their standard values and use R = 0.08206.
PV = nRT
(1.00 atm) (V) = (1.00 mol) (0.08206 L atm mol¯1 K¯1) (273 K)
V = 22.4 L
