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 Does “mM” mean in Chemistry? Explanation: Millimolar (mM) concentrations are often used for convenience when working with solutions of small quantities of substances. One millimolar (1 mM) is equal to one-thousandth of a mole per liter (1/1000 mol/L).If a solution has a 5 millimol...
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 the abundance of a constituent divided by the total volum...
Concentration refers to the amount of a substance in a given volume, while strength typically measures the effect or potency of a substance.
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...
How are absorbance and concentration related? (a) What are the principles of chemistry? (b) How are they applied? What is mass spectrometry and how does it work? In a series of titration experiments, why is it that you always work with the smallest sample first? Explain. ...
Isotherms are used to describe adsorption because the temperature has a significant effect on the process. The quantity of adsorbate bound to the adsorbent is expressed as a function of the pressure of concentration at a constant temperature. ...

The global mean OH concentration ([OH]GM) has been used as an indicator of the atmospheric oxidizing efficiency and its changes over time. It is also used for evaluating the performance of atmospheric chemistry models by comparing with other models or with observationally-based reference [OH]GM...
Titration is a quantitative analytical technique used to determine the unknown concentration of an analyte of interest (the substance to be analyzed). It is performed by gradually adding an exactly known quantity of a substance (the tritrant), which reacts with our analyte in a definite proportio...
