For covalent substances, the formula represents the numbers and types of atoms composing a single molecule of the substance; therefore, the formula mass may be correctly referred to as a molecular mass. The percent composition of a compound can be easily determined from the chemical formula of the compound. In percent solutions, the amount (weight or volume) of a solute is expressed as a percentage of the total solution weight or volume. The formula mass for an ionic compound is calculated in the same way as the formula mass for covalent compounds: by summing the average atomic masses of all the atoms in the compounds formula. or volume (L, mL, L, etc.). The concentration of Cl ion in a sample of H2O is 15.0 ppm. This is because naturally occurring carbon is a mixture of the isotopes 12C, 13C and 14C which have masses of 12 Da, 13.003355 Da, and 14.003242 Da respectively.
