Avogadro's constant -- 6.02 x 10^23 -- describes the number of atoms in a mole of an element. Hence, there are 0.3125 moles of oxygen are present in 10 g of oxygen gas. For further confirmation, you can use a free grams to moles calculator that is also available on our website. Scientists express atomic weights in terms of grams per mole, so the resulting equation looks like this: atomic weight expressed in atomic mass units = grams/mole. The SI base unit for amount of substance is the mole. However, it also defines the mole, so we can also express NA as 6.02 1023 mol1; in this form, it is properly known as Avogadro's constant. The substance can be atoms, molecules or ions of a substance. Thus, 48 g of Mg is equivalent to $12.04 \times {10^{23}}$ atoms.
