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).
What pH Stands For The term pH is used to mean the power of hydrogen within the solution. There is some debate within the scientific community of where the p comes from, but it now is indicative of the word power.
