Take the molecular mass and divide by the result from the previous step. Multiply the atoms in the empirical formula by this result. QUESTIONS. Calculate the empirical formula for each of the following substances. You should use the following values for relative atomic mass: H = 1 N = 14 O = 16 P = 31 S = 32 Cu = 64. 1.To calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar mass (180.159 g/mole, determined from the chemical formula) to calculate the percentages of each of its elements: %C = 9molC × molar mass C molar mass C9H8O4 × 100 = 9 ...

Empirical Formulas. An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H 2 O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H 2 O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen.We can also work backwards from molar ratios since if we know the molar amounts of ...The sulfur and oxygen molecules, sulfur monoxide, and disulfuric dioxide have the same empirical formula.
