Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element's symbol.
This information can be gathered from the chemical formula of the substance. A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound.It contains the symbols of the atoms of the elements present in the compound, as well as how many there are for each element in the form of subscripts.his information can be gathered from the chemical formula of the substance.
