Just in case you didn't know, one elephant has one trunk and four legs, and one molecule of methane (CH4) contains one carbon atom and four hydrogen atoms. So, one mole is equal to 6.02 x 10²³ atoms (or molecules) of a substance, in the same way that 12 of anything makes up a dozen.

The inactive ingredients in toothpaste provide stability and esthetics. These ingredients include binders, surfactants, buffering agents, humectants (glycerin and sorbitol), preservatives, sweeteners,flavorings, and dyes. Humectants are added to retain moisture so that the toothpaste does not dry out.

A The empirical formula—Ca3(PO4)2—indicates that the simplest electrically neutral unit of calcium phosphate contains three Ca2+ ions and two PO43− ions. The formula mass of this molecular unit is calculated by adding together the atomic masses of three calcium atoms, two phosphorus atoms, and eight oxygen atoms.
