WebAug 4, 2024 · Multiply each of the moles by the smallest whole number that will convert each into a whole number. Write the empirical formula. Example 10.12. 1: Determining the Empirical Formula of a Compound. A compound of iron and oxygen is analyzed and found to contain 69.94 % iron and 30.06 % oxygen. Find the empirical formula of the compound. Webusing the masses of CO2 and H20, find the respective amounts of carbon, hydrogen, and oxygen through dimensional analysis. Use the method to find empiricle formulas (divide masses of elements by respective atomic masses, then divide them all by the smallest quotient). thats how many of each element is in the empirical formula.
