For example, to convert moles of a substance to mass, we use the relationship, \( (moles)(molar \; mass) \rightarrow mass \tag{1.71} \), \( moles\left ( \dfrac{grams}{mole} \right ) = grams \), \( \left ( \dfrac{mass}{molar\; mass} \right )\rightarrow moles \tag{1.72}\), \( \left ( \dfrac{grams}{grams/mole} \right )=grams\left ( \dfrac{mole}{grams} \right )=moles \). We also described the law of multiple proportions, which states that the ratios of the masses of elements that form a series of compounds are small whole numbers. For every molecule of C12H22O11, there are 12 carbon atoms, aka 1:12.

For example, the mass of 1 mol of magnesium (atomic mass = 24.305 amu) is 24.305 g. Because the atomic mass of magnesium (24.305 amu) is slightly more than twice that of a carbon-12 atom (12 amu), the mass of 1 mol of magnesium atoms (24.305 g) is slightly more than twice that of 1 mol of carbon-12 (12 g).
