An eastern mole weights about mmole75gm_{\text{mole}}75\ \text{g}mmole75g (think of a big egg). Our moles to molecules calculator also provides the number of formula units in case of ionic compounds. In other words, molality is the number of moles of solute (dissolved material) per kilogram of solvent (where the solute is dissolved in). Chemists rarely make a gram of a substance react with a gram of another, hoping that this would give them some reference: a gram of mercury contains far fewer atoms than a gram of hydrogen. While molarity describes the amount of substance per unit volume of solution, molality defines the concentration as the amount of substance per unit mass of the solvent.
