Empirical Formula Worksheet Empirical Formula - a formula showing the smallest whole-number mole ratio. 1. Convert the grams of each element to moles. 2. To find the simplest ratio, divide each element's mole value by the smallest mole value. This will ensure a something to 1 ratio. 3.EMPIRICAL FORMULA WORKSHEET WITH ANSWERS | Teaching Resources Find the empirical formula and the molecular formula of this compound. 1.116 g 1 mole = 0.0200 mole Fe 55.8 g Since the efm and the mfm are nearly identical, the ef and the mf must also be identical: Fe2O3 .480 g 1 mole = 0.0300 mole O 16.0 g efm: 2 (55.8) + 3 (16.0) = 159.6 g/mol mfm: 32.0 g O2 5 = 160.

Empirical formulas represent the lowest whole number ratio of atoms in a compound. These calculations involve mole conversions and then using the ratio of moles as the subscripts in a chemical formula. Molecular formulas tell you the exact number of atoms in a compound and are always some whole number multiple of the empirical formula. 1. The molecular formula and empirical formula are right. As we known, empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. If the compound molecular formula is C2H4Cl2, so we divide it with 2, 4, and 2 GCD / greatest common divisor. The GCD is 2, so the empirical formula is CH2Cl.
