Home > Molar volume

In chemistry, the molar volume of a substance is the volume of one mole of that substance. It can be computed as the substance's atomic or molecular weight, divided by its density. The SI unit of molar volume is cubic metres per mole (m3mol-1).

For an ideal gas, the standard molar volume is the volume that is occumpied by one mole of substance (in gasseous form) at standard temperature and pressure (STP) of 273.15 K (H2O freezing temperature) and 101325 Pa (1 atm). It is 0.022414 m3mol-1 or 22.42 L/mol and is directly related to the universal gas constant R in the ideal gas law.

Cubic centimetres (cm3) a measure of volume one million times smaller than a cubic metre, are sometimes also used, to give units of cm3mol-1.

The molar volume is usually given for a solidA solid is a state of matter, characterized by a definite volume and a definite shape (i. it resists deformation). Within a solid, atoms/ molecules are relatively close together, or "rigid"; however, this does not prevent the solid from becoming deformed substance at 298.15 K (temperature of standard stateIn chemistry, the standard state of a material is its state at 1 standard atmosphere (101 325 pascals) and 25 degrees Celsius (298. 15 kelvin). When the standard state is referred to in a chemical reaction, it also includes the condition that all solution). Apart from temperature and density, it depends on phase and allotrope of the substance.







Chemical properties Physical quantityA physical quantity is the result of measurement and usually expressed as the product of a numerical value and a physical unit (whereby SI units are usually preferred). Example : P 42. 3 x 103 W 42. 3 kW where P represents the physical quantity for power

Cubic zirconiaCubic Zirconia (or CZ is zirconium oxide ( ZrO), a mineral that is extremely rare in nature, but is widely synthesized for use as a diamond simulant. The synthesized material is hard, optically flawless and usually colourless, but may be made in a varietyCubic centimetreA cubic centimetre cm is an SI derived unit of volume, equal to the volume of a cube with side length of 1 centi metre. It was the basic unit of volume of the CGS system of units. In SI units: 1 cm³ 10−6 cubic metres 1 milli litre (mL) The abbreviatCubic decimetreA cubic decimetre (symbol dm is an SI derived unit of volume. It is the volume of a cube of side length 1 decimetre (10 cm). In SI units: 1 dm³ 10−3 cubic metres 1 cubic decimetre is equal to 1 litre. See 1 E-3 m³ for a comparison with other volumes
Cubic metreThe cubic metre (symbol m is the SI derived unit of volume. It is the volume of a cube with edges one metre in length. Older, now unofficial, equivalents were the stere and the kilolitre''. 1 cubic metre is equal to: 1,000 litres 1,000 cubic decimetres 1,Cubic equationA cubic equation is a polynomial equation in which the highest occurring power of the unknown x is the third power. An example is the equation :2''x''3 4''x''2 + 3''x 4 0 and the general form may be written as a x''3 + a x''2 + a x + a 0 where we will assCubic inchA cubic inch is the volume of a cube which is one inch long on each edge. It is equal to 16. Historically, internal combustion engines produced in the United States had their engine displacements stated in cubic inches. In the case of automobile engines,
