6.022×1023

Explanation:

A mole of anything is just a way of expressing how many of something there are.

If I were referring to a mole of ballerina dancers, I would be talking about 6.022×1023 ballerina dancers.

The reason a mole is 6.022×1023 is because one mole of hydrogen atoms weighs about 1 gram.
