Mathematically, by mass: ppm=gsolutegsolution=mgsolutekgsolution In the case of very dilute aqueous solutions, a concentration of 1.0 ppm is equal to 1.0 g of solute per 1.0 mL, which equals 1.0 g solution. Parts per billion is defined in a similar fashion.
WebNov 7, 2024 · Molar refers to the unit of concentration molarity, which is equal to the number of moles per liter of a solution. In chemistry, the term most often refers to molar concentration of a solute in a solution. Molar concentration has the units mol/L or M. WebThe atomic mass of an element is defined as the mass of an atom of that element, while the molar mass is the mass of one mole of that element. Since one mole of any substance contains Avogadro's number (6.02 x 10^23) of particles, the molar mass of an element in grams is equal to its atomic mass in atomic mass units (amu).
