Unit stoichiometry mole mole calculations wksh 1 answer key

For moles, the unit is simply moles. The number of atoms is just a number; therefore it is dimensionless, i.e., it does not any units. 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.
