The equation of 6.02 times 10 to the 23rd power is equal to 602,000,000,000,000,000,000,000, or 602 followed by 21 zeros. This number is read aloud as "602 sextillion" and is a reference to Avogadro's number.
Know MoreAccording to the Encyclopaedia Britannica, Avogadro’s number is the number of units, usually atoms or molecules, found in one mole of any substance. This means that a mole, by definition, always contains the same number of units, regardless of the substance.
A mole is related to atomic weight or mass. For example, one mole of carbon-12 atoms has an atomic weight of 12 grams, while a mole of oxygen, which would also contain an Avogadro's number of units, has an atomic weight of 16 grams. This shows that oxygen has a greater mass than carbon.
