Understanding the Mole. Introduction: The relative mass of an object is how many times more massive the object is than a standard object. The atomic masses of atoms are all relative masses. They can be considered relative to any particular element. Historically, both oxygen and carbon have served as the reference standard.

CHEMISTRY WORKSHEET # 5 MOLE PROBLEMS—MOLAR VOLUME OF A GAS. We have learned that a mole is a mass of material and number of particles. A mole can also be a measure of volume when we are talking about gases. You may remember from previous science classes that all gases behave basically the same as far as the physical properties of temperature ...

The molecules “fill” the remaining space by moving rapidly through it. So the difference in size between large molecules and small molecules is insignificant compared to the total volume the gas occupies. At standard temperature and presssure (STP = OoCelcius and 1.00 atm pressure) one mole of any gas will have a volume of 22.4 liters.
