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...
Concentration The degree of compactness of a substance. The concentration of pollutants in the air is a health concern. 1 Amount Overall quantity regardless of concentration. The amount of sugar in the jar was enough for several batches of cookies. 1 Concentration In chemistry, concentration is th...
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...
To some extent, whether a mixture is classified as homogeneous or heterogeneous is a matter of scale. For example, mist may appear to be homogeneous when viewed on a large scale, yet if magnified, the concentration of water won't be uniform from one area to another. Similarly, somemixtures...
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. Strength The quality or state of being physically...

concentration; in the US, 80 proof is precisely equal to 40 volume-percent. The term, however, was first defined in the UK as 7/4, and not 1/2, the percent concentration of alcohol. This is because the desirability of the spirits were proven by the ignition of an admixture with ...
