Show In this post, you’ll learn how to find the empirical and molecular formula of an unknown compound when given the mass percent of the compound. First, we’ll start by going over all the steps. Then we’ll apply the step by going through an example. Steps for Finding The Empirical Formula Given Mass Percent
ExampleLets work through this example together and go through it step by step. What is the empirical formula for a compound containing 38.8% carbon, 16.2 % hydrogen, and 45.1% nitrogen? Steps
Steps for Finding The Molecular Formula from Empirical FormulaTo be able to find the molecular formula, you’ll need to given the molar mass of the compound.
ExampleLet’s continue with the example we were working through. If the molar mass of the unknown compound is 62.11 g/mol, what is the molecular formula. Steps
And that’s it! Follow the steps, practice, and you’ll be able to solve these types of problems with no problem. Soon you’ll be conquering chemistry.
