According to wikipedia…
In chemistry and related fields, the molar volume, symbol V m, or of a substance is the volume occupied by one mole of it at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ).

What is Molar Volume
The molar volume is the volume occupied by one mole of any gas, at room temperature and pressure.
The molar volume is equal to 24 dm 3 (24,000 cm 3).

How is molar volume calculated
Dividing the molar mass (M) by mass density (ρ).
At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound.
It can be calculated by dividing the molar mass (M) by mass density (ρ).
Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.
Molar volume formula
- Amount of materia (n);
- Volume (V);
- Molar Volume (Vm).
n = V/Vm.
Molar volume units
SI unit of cubic metres per mole (m3/mol)
It has the SI unit of cubic metres per mole (m3/mol), although it is typically more practical to use the units cubic decimetres per mole (dm3/mol) for gases, and cubic centimetres per mole (cm3/mol) for liquids and solids.
Molar volume from density
Dividing the molar mass (M) by mass density (ρ)
At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound.
It can be calculated by dividing the molar mass (M) by mass density (ρ).
Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.
Molar volume symbol
The molar volume (symbol Vm) of a substance is the volume occupied by one mole of the substance at a given temperature and pressure.
It is equal to the molecular mass (M) of the substance divided by its density (ρ) at the given temperature and pressure: It has an SI unit of cubic metres per mole (m3/mol).
Molar volume to volume
22.4 liters / mol
The most common example to illustrate is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.
4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.
How to Calculate Excess Molar Volume
(2) V m E = ∑ i 1 ρ - 1 ρ i x i M i.
Using the measured densities ρ, excess molar volumes are calculated by the following equation above.
ρ is density of mixture and ρi, xi and Mi are density, mole fraction and molar mass of pure component i, respectively.
How to Find Molar Volume From Density
Multiply the volume by the density to get the mass.
Divide the mass by the molar mass to get the number of moles.
