Molar Mass Formula-Steps to find the Molar Mass with Solved …
Web2 jan. 2024 · Step 1: First, let’s calculate the empirical formula molar mass. Empirical formula molar mass (EFM) = 1.00794 + 15.9994 = 2.01588 + 31.9988 = 17.007 g/mol Step 2: Now, divide the molar mass of the given compound by the empirical formula mass. n = Molar mass/EMF = 60.052/17.007 = 2 Step 3: Molecular Formula = n × (Empirical formula) molecular mass = (1 x 14.0067) + (3 x 1.00794) molecular mass = 14.0067 + 3.02382 molecular mass = 17.0305 Note the calculator will give an answer of 17.03052, but the reported answer contains fewer significant figures because there are six significant digits in the atomic mass values used in the calculation.
