Ideal Gases
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas:
-
- .
Hence, 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 = 8.314 4621(75) J mol−1 K−1, that is a relative standard uncertainty of 9.1×10−7, according to the 2010 CODATA recommended value. The molar volume of an ideal gas at 100 kPa (1 bar) is
- 22.710 980(38) dm3/mol at 0 °C
- 24.789 598(42) dm3/mol at 25 °C
The molar volume of an ideal gas at 1 atmosphere of pressure is
- 22.414 L/mol at 0 °C
- 24.465 L/mol at 25 °C

Famous quotes containing the words ideal and/or gases:
“Truth is that concordance of an abstract statement with the ideal limit towards which endless investigation would tend to bring scientific belief, which concordance the abstract statement may possess by virtue of the confession of its inaccuracy and one-sidedness, and this confession is an essential ingredient of truth.”
—Charles Sanders Peirce (1839–1914)
“The bird is not in its ounces and inches, but in its relations to Nature; and the skin or skeleton you show me, is no more a heron, than a heap of ashes or a bottle of gases into which his body has been reduced, is Dante or Washington.”
—Ralph Waldo Emerson (1803–1882)
