A mole is a unit of measurement that is assigned to the quantity of any substance. It is the molarity of a given substance, and it is often measured in mols per meter.
A molecule is a group of atoms that are combined by a chemical reaction.
The unit of a mole is “mol”.
The number of molecules present in a substance is determined by the number of “mols” present in the substance.
The mole of a substance is equal to the Avogadro’s number, 6.02 times 10²³.
The molarity of a substance is estimated by the amount of the substance, multiplied by 1 Avogadro’s number (6.02 times 10²³).
For example, if one egg is a molecule, it means that 1 mol of the egg equals one Avogadro’s number (6.02 times 10²³). However, the number of mols in 12 eggs equals 12 times 6.02 times 10²³, which equals 7.224 times 10²³.
