What m and M Mean in Chemistry. Both m and M are units of the concentration of a chemical solution. The lower case m indicates molality, which is calculated using moles of solute per kilograms of solvent. A solution using these units is called a molal solution (e.g., 0,1 m NaOH is a 0.1 molal solution of sodium hydroxide).
Precipitation in chemistry refers to the creation of a solid within a solution or within another solid during the process of diffusion. During this process, the solid formed is known as the precipitate. What causes the solid to form is known as the precipitant, and the supernate or supernatant is the area above the precipitate.
