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 is Tg chemistry? In chemistry, Tg is the glass transition temperature of an amorphous polymer. It is the individual polymer's fixed temperature at which point it either becomes flexible when tâ¦he actual temperature of it is higher than the Tg, or it becomes rigid, when the actual temperature is lower than its Tg.
