The molecular mass of a compound is the
WebAug 25, 2024 · Step 5: The molar mass of the compound is known to us, M = 58.12 g mol −1. The empirical mass of the compound is obtained by adding the molar mass of individual elements. Let the ratio of the molar mass to empirical mass be r. Thus, multiplying 2 to the empirical formula, 2 × C 2 H 5 = C 4 H 10. WebJan 26, 2024 · 1st Step: Calculate the empirical formula from percentage composition. 2nd Step: Calculate the Empirical Formula mass (EFM) by adding up the molar atomic masses of all atoms constituting the formula. 3rd Step: Determination of the Molar Mass of the given compound. 4th Step: Determination of the value ‘n’.
