The number of atoms is just a number; therefore it is dimensionless, i.e., it does not any units. The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Calculator Academy© - All Rights Reserved 2020. Thus, in order to be able to determine how many atoms we are working with, chemists use the unit of a mole. Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams. Rearrange the formula to find Avogadro's constant: number of atoms / moles = Avogadro's number So on the left-hand side, we have no units / moles , which can be expressed as mol -1 .
