WebMay 7, 2024 · What m and M Mean in Chemistry . Both m and M are units of the concentration of a chemical solution. The lowercase 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). WebConcentrations may be measured using various units, with one very useful unit being Molarity. The solute concentration of a solution may be decreased by adding solvent, a process referred to as dilution. The dilution equation is a simple relation between concentrations and volumes of a solution before and after dilution. Key Equations
