The chemical formula of potassium bromide is KBr, showing that each formula unit contains equal numbers of potassium and bromine atoms. The gram atomic masses of potassium and bromine are 39.0983 and 70.904 respectively. Therefore, the mass fraction of bromine in KBr is 70.904/(70.904 + 39.0983) or about 0.644568. 50.0 g of potassium bromide therefore contains 32.2 g of bromine, to the justified number of significant digits.
