There are two binary compounds of mercury and oxygen. The decomposition of 0.64 98 g first compoundleaves a residue of 0.601 8 g pure mercury while the decomposition of 0.4172 g second compound results in a mass loss of 0.016 g oxygen. The empirical formulas of both the compounds are to be identified. Concept introduction: For any compound, its empirical formula represents the ratio of atoms present in it. The most popular technique for evaluating the chemical formula of a compound first involves the calculation of the masses of its component elements. The moles of each element concerning each other are calculated. These moles are changed into a ratio of the whole number, which is used for the derivation of the empirical formula of a compound.
