Description of a Mole
A mole is 4 to 7 inches in length with paddle-shaped feet and prominent digging claws. It has an elongated head and snout, small eyes, and no external ears. The short black-to-brownish-gray fur has no grain, which allows the mole to move easily forward and backward in the tunnels.

Why is a mole 6.022 x10 23?
The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×1023 elementary entities of the substance.
What number is the mole?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
How many grams does 1 mole of gold weigh?
Furthermore, the atomic mass of gold is 196.9665. That means that one mole of gold weighs 196.9665 grams (196.9665 g/mol). Based on that information, to convert 1 moles of gold to grams, we multiply 1 moles of gold by 196.9665.
