Final answer:
Molarity, defined as moles of solute per liter of solution, is a measurement of concentration frequently used in chemistry for solution analysis.
Step-by-step explanation:
The measurement of concentration refers to the quantity of solute within a given quantity of solution. Several units are used to express concentration, but when it comes to chemical reactions and solutions, molarity is particularly significant. Molarity is defined as the number of moles of solute per liter of solution and is a central concept in chemistry for solutions analysis.
Molarity is calculated by dividing the moles of solute by the volume of solution in liters. Concentration can also be expressed in other units such as percent solutions, which are based on the mass or volume of the solute in relation to the solution and are used for expressing higher concentrations. For very dilute solutions, parts per million (ppm) or parts per billion (ppb) are used, which are especially prevalent in environmental and medical contexts.
