Lets move on! \[\dfrac{80 \;atoms}{6.02 \times 10^{23} \; atoms\; mol^{-1}} = 1.33 \times 10^{-22} mol \nonumber\]. Therefore, number of atoms in 48 g of Mg = 2 mol $ \times $ $6.022 \times {10^ {23}}$atoms/mol= \ [12.04 \times {10^ {23}}\] atoms. Thus, 48 g of Mg is equivalent to $12.04 \times {10^{23}}$ atoms. The atomic weight, molecular weight, or formula weight of one mole of the fundamental units (atoms, molecules, or groups of atoms that correspond to the formula of a pure substance) is the ratio of its mass to 1/12 the mass of one mole of C12 atoms, and being a ratio, is dimensionless. It is important always to bear in mind that the mole is a number and not a mass. The mass of the oxygen atom will be 4/3 greater (from Example \(\PageIndex{1}\)): \[ \left( \dfrac{4}{3} \right) 1.99 \times 10^{23} \, g = 2.66 \times 10^{23} \, g \text{ (per oxygen atom)} \nonumber\]. Express the relationship of the three pieces of information you need to calculate the number of atoms in the sample in the form of an equation. This means that the atom of oxygen has a mass that is, \[\dfrac{16\, \cancel{u}}{12\, \cancel{u}} = \dfrac{4}{3} 1.33 \nonumber\]. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. How many atoms of magnesium are in 1.00 g? Atomic mass O is 15.9994. Here the mole is the quantity that predicts the particles in a certain mass of the compound and you can determine it by using the best mole calculator in a span of moments.
