602,214,076
602,214,076 is the digit string of the Avogadro constant, exactly 6.02214076 × 10²³ per mole since 2019.
- Even
- Composite
Why 602,214,076 is special
The mole used to be defined as the number of atoms in twelve grams of carbon-12, which made it depend on the kilogram. Fixing the constant made the mole a pure count, and the number stopped being something to measure.
