Concentration - Wikipedia, the free encyclopedia In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration
Concentration: Percentage of Solution by Mass/Volume Concentration: Percentage of Solution by Mass/Volume Basic Concept The concentration of a solution is often expressed as the percentage of solute in the total amount of solution. For the extremely dilute solutions the concentration unit parts per million
Volume fraction - Wikipedia, the free encyclopedia Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18. It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%. The volume fraction coincides with the volume concentrat
