WebA molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.) Molecular formulas are also used as abbreviations for the names of compounds. WebJan 2, 2024 · The molecular formula of a chemical compound can be found in the following ways: Using Composition and Molecular Weight Step 1: Multiply the molecular weight with the given component percentage. Step 2: Divide each value obtained by the atomic weight of that atom. Step 3: Round off the obtained values to the closest whole number.
