The concentration of a solution formed by diluting 25.0 ml of a 3.2 m nacl solution to 135.0 ml is 0.60 mol
M1V1=M2V2
M2=M1V1/V2
M2= 3.2×25.0 ÷ 135.0
M2=0.60 mol.
The term "concentration" in chemistry refers to the elements that make up a mixture or solution. Here's how concentration is defined and how it can be calculated using various techniques. Concentration in chemistry refers to the quantity of a substance in a given area. The ratio of the solute in a solution to the solvent or total solution is another way to define concentration. In order to express concentration, mass per unit volume is typically used. The solute concentration can, however, also be expressed in moles or volumetric units. Concentration may be expressed as per unit mass rather than volume. Although concentration is typically used to describe chemical solutions, it can be calculated for any mixture. Concentration Examples in Units: g/cm3, kg/l, M, m, N, and kg/L
