OK first some corrections That was 73 by mass not 73 Hg and 27 by mass not 27 Cl But more importantly you have mistaken the number of moles a measure of the number of atoms of Hg Cl for their atomic weights a measure of the average weight of a collection of atoms of that element Number of moles Your answers should be whole numbers and are used as the subscripts in the chemical formula Step 4 Use the mole ratio to write the empirical formula Example Find the empirical formula for the compound that contains 42 05 g of nitrogen and 95 95 g of oxygen Step 1 Skip you were given grams
