In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solute concentration may al...

What is an analytical concentration in analytical chemistry? Types of Concentrations: The concentration of a substance can be measured in several ways. It may be grams over liters (gram concentration), moles over liters (molar concentration), or mililiters per 100 mililiters (volume concentration...

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.

solution concentration. It does not involve volume, however, but only weight — for both solute and solvent. This means molality is not temperature-dependent, making it the unit of choice in those areas of chemistry involving "colligative" properties — those properties involving numbers of ...
