It is important to be able to convert units from and into units of moles. The mole is a unit for count, as is the dozen. A dozen is 12 items, but a mole is 602 000 000 000 000 000 000 000 , or 6.02 × 1023 particles. Using the periodic table we can find the molar mass, or the mass of a mole of a substance. The molar volume is the volume of a mole of substance. Mole Conversion Strategy All gases have the same molar volume when measured at standard temperature and pressure (STP) : 22.4 L/mol. Mass These values allow the conversion of grams, liters, or molar mass (g/mol) (grams) particles into moles. Volume of gas 22.4 L/mol (liters)
