**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.

According 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.
