Moles to Molecules Formula

The following equation can be used to convert moles into molecules.

N = n × NA
  • Where N is the number of specified entities (molecules for this conversion)
  • n is the amount of substance in mol; NA = 6.02214076 × 1023 mol⁻¹ exactly

To calculate the number of molecules, multiply the amount in mol by exactly 6.02214076 × 1023 mol⁻¹. For the reverse conversion, divide the count by this constant. In mass mode, first divide mass in grams by the corresponding molar mass in g/mol. Choose the entity corresponding to the entered amount or molar mass; selecting atoms does not infer the number of atoms per molecule.

Moles to Molecules Definition

The mole (symbol mol) is the SI unit of amount of substance. One mole contains exactly 6.02214076 × 1023 specified elementary entities, such as molecules, atoms, ions or electrons. For 0.5 mol of molecules, the count is 3.01107038 × 1023 molecules. The exact conversion constant does not remove uncertainty in a measured amount.
