Standard molar volume

For one mole of an ideal gas:
V=R.Tp with n = 1

For all ideal gases, one mole of gas takes up a volume of 22.4141 L. on when the pressure is 1.013 bar = 1 atm and the temperature 0 ° C amounts to. This volume is called the standard molar volume.

Unfortunately the temperature corresponds to 0 ° C not the standard thermodynamic temperature of 25 ° C. The molar volume of the latter is 24.47 L..

From the general gas equation, a conversion formula for changed conditions can be set up for a certain amount of gas under known conditions. the end

Condition 1
p1V1=nR.T1
Condition 2
p2V2=nR.T2
is obtained by eliminating nR.
p1V1T1=p2V2T2
