amagat density

[Etymology: E. H. Amagat; Netherlands, France 1841-1915] molecular density, molecular volume For pressurised gases, the amagat volume is that of 1 mole of the gas at s.t.p., which is 22.414 0~ L (the standard volume) for ideal gas and close to that figure for real gases; the amagat unit for volume for a real gas is the ratio of its figure to that of ideal gas. The reciprocal of the above figure shows the amagat density to be 44.614 98~ mol·kL^-1 for the ideal gas. The amagat unit for density is the ratio of the amagat density of real gas to that of the ideal, hence the reciprocal of the amagat unit for volume.
