### Molar volume - Wikipedi

In chemistry and related fields, the molar volume, symbol Vm, or of a substance is the occupied volume divided by the amount of substance at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ) The SI unit of molar volume is cubic meters per mole (m 3 /mol). However, because that is such a large volume, other units are usually used. Cubic centimeters per mole (cm 3 /mol) is used for solids and liquids. Cubic decimeters per mole (dm 3 /mol) may be used for gases Molar volume is the space occupied by one mole of a substance. This term is used in chemistry to determine the molecular volume reflected in cubic meters per mol (m 3 x mol -1). A mole is the unit contemplated by the International System of Units that allows to measure and express a certain amount of substance 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 The molar volume(symbol Vm) of a substance is the volumeoccupied by one moleof the substance at a given temperatureand pressure. It has an SI unitof cubic metresper mole (m3/mol)

• And, for a given temperature and pressure, the molar volume is the same for all ideal gases, and is known to the same precision as the gas constant: R = 0.082 057 338 (47) L atm K−1 mol−1, that is a relative standard uncertainty of 5.7×10−7, according to the 2014 CODATA recommended value.
• It should be noted that while the volume of a substance is never negative, the partial molar volume can be. An example of this appears in the dissolution of a strong electrolyte in water. Because the water molecules in the solvation sphere of the ions are physically closer together than they are in bulk pure water, there is a volume decrease.
