Reaction rates are usually expressed as the concentration of reactant consumed or the concentration of product formed per unit time. The units are thus moles per liter per unit time, written as M/s, M/min, or M/h.
Units of Measure. A unit of measure is the amount of chemical found in a specific volume of waterâfor example, pounds/gallon or teaspoons/gallon. It is also called concentration units, or simply units. The four common units of measure used in drinking water analysis results are mg/L, Âµg/L, ppm, and ppb. Milligrams per liter (mg/L) is equivalent to ppm (parts per million). To convert mg/L to Âµg/L simply multiply by 1000 (1 mg/L = 1000 Âµg/L).
