Introduction to Moles
Tyler DeWitt・2 minutes read
A mole is a massive number of things, with 602 hexillion in a mole, often confused with a molecule but represented by Avogadro's number 6.02 times 10 to the 23rd for convenience in calculations. The size difference between a mole of jellybeans as large as Earth and a mole of tiny atoms like sulfur fitting into a small container is vast.
Insights
- A mole is a term for a specific number of things, not to be confused with a molecule, consisting of 602 hexillion items and represented by Avogadro's number for easier calculations.
- The concept of a mole showcases the immense scale differences, with a mole of jellybeans being as large as Earth, while a mole of atoms, like sulfur atoms, can fit into a small container due to their minuscule size.

What is a mole in chemistry?
A mole is a specific number of things, equivalent to 602 hexillion.
How does Avogadro's number relate to a mole?
Avogadro's number, 6.02 x 10^23, abbreviates the vast number in a mole.
Can a mole be anything other than atoms?
Yes, a mole can represent any substance, like doughnuts or jellybeans.
How does the size of a mole of jellybeans compare to a mole of atoms?
A mole of jellybeans is as large as Earth, while a mole of atoms fits in a small container.
Why do people often confuse a mole with a molecule?
People confuse a mole with a molecule due to similar-sounding names, but a mole refers to a vast number, not a molecule.

Understanding the Enormity of a Mole
- A mole is a name for a specific number of things, similar to a dozen, but much larger, with 602 hexillion things in a mole.
- People often confuse a mole with the word "molecule," but a mole refers to a group of 602 hexillion things, not a molecule.
- Avogadro's number, 6.02 times 10 to the 23rd, is used to abbreviate the gigantic number of 602 hexillion for convenience in calculations.
- A mole can be of anything, like doughnuts or jellybeans, with a mole of jellybeans being as large as the planet Earth.
- A mole of atoms, like sulfur atoms, is much smaller than a mole of jellybeans, fitting into a small container due to the tiny size of atoms.
- The key points include understanding what a mole is, the vast number of things in a mole, abbreviating the number using scientific notation, and the vast difference in size between a mole of jellybeans and a mole of atoms.
