Chemistry - Molar volume
The molar volume of a gas is simply the volume occupied by one mole of the
gas. Molar volumes are quoted at specific temperatures and pressures
because the chemical amount of gas present in a sample also depends upon
temperature and pressure .
Ideal gases - those that obey the general gas equation - are assumed to
have the same molar volume at the same specific temperature and pressure.
There are two general sets of conditions for which molar volumes are
STP conditions have long been used as a reference point for gases. Quoting
volumes at specified temperatures and pressures ensures that accurate
comparisons can be made about chemical amounts present.
