mol

Advanced 💻 Tech / IT

Definition

The SI unit representing 6.022 × 10²³ of literally any particle (atoms, molecules, ions—you name it). Chemists use this when saying 'a billion billion billion' would make them sound insane. It's mathematics' way of pretending the incomprehensibly vast is totally manageable.

Example Usage

We need 2 moles of hydrogen gas to complete the reaction.
