The following expression can be used to express the relationship between the number of moles and Avogadro’s Number: Number of atoms/molecules/ions = n x N A. We know this is true because Avogadro’s Law says that the quotient of the volume and the number of moles is constant for an ideal gas. Performing the calculation yields: 1.02 × 10 23 is called Avogadro’s number, the number of representative particles in a mole. Remember, the Avogadro’s number shows how many particles, which can be atoms, molecules, or ions, there are in one mole of a sample and because it is related to moles, we need to first convert the mass to moles. The number of atoms in a weighed sample is related to electron .
