If the substance is molecular in nature, its molecular formula can be determined from the empirical formula if the molecular mass is also known. Volumetric Analysis Solutions of known molarity can be formed either by adding a measured mass of solute and diluting it to a known volume or by the dilution of a more concentrated solution of known ...
