As we described in Section 4. The number of things in a mole is large, very large 6. We are all familiar with common copy-machine paper that comes in sheet reams. If you stacked up 6. The mole is a huge number, and by appreciating this, you can also gain an understanding of how small molecules and atoms really are. Chemists work simultaneously on the level of individual atoms, and on the level of samples large enough to work with in the laboratory. The concept that allows us to bridge these two scales is molar mass. Molar mass is defined as the mass in grams of one mole of a substance. The atomic mass of an element is the relative average of all of the naturally occurring isotopes of that element and atomic mass is the number that appears in the periodic table. We have defined a mole based on the isotopic atomic mass of carbon

Molar mass of oxygen 16 or 32

The number of moles in a system can be determined using the atomic mass of an element, which can be found on the periodic table. This mass is usually an average of the abundant forms of that element found on earth. An element's mass is listed as the average of all its isotopes on earth. The mass of a mole of substance is called the molar mass of that substance. The molar mass is used to convert grams of a substance to moles and is used often in chemistry. If the mass of a substance is known, the number of moles in the substance can be calculated.
