## The Mole Concept

The Mole Concept. Avogadro’s Number. Avogadro’s Number (symbol N ) is the number of atoms in 12.01 grams of carbon. Its numerical value is 6.02 × 10 23. Therefore, a 12.01 g sample of carbon contains 6.02 × 10 23 carbon atoms. The Mole.

## How Big is a Mole?

How Big is a Mole?. One mole of marbles would cover the entire Earth (oceans included) for a depth of two miles. One mole of \$1 bills stacked one on top of another would reach from the Sun to Pluto and back 7.5 million times. It would take light 9500 years to travel from the bottom
