To determine the percentage composition of a compound of your choice and then use these percentage composition to determine the molecular formulas of the same, after that find the empirical formula with the help of percentage composition data. Concept Introduction: Percentage by mass of any element in the compound is the amount of that element in the total amount of the compound. The chemical formula which represents the simplest whole number atoms ratio present in the compound is said to be empirical formula. The chemical formula which shows the actual number of every atoms present in the compound is known as molecular formula. Number of moles can be calculated as follows; Nuumber of moles = mass in g molar mass .
