what is concentration in chemistry
concentration - the strength of a solution; number of molecules of a substance in a given volume. property - a basic or essential attribute shared by all members of a class; a study of the physical properties of atomic particles. titer, titre - the concentration of a solution as determined by titration.
Concentration is most commonly expressed as molarity. A one molar solution contains one mol of solute per liter of solution (B+C). When making solutions in the lab, the mols of solute can be determined from the measured mass of the molecule and its molecular weight.
