This collection offers common abbreviations and acronyms beginning with the letters U and V used in chemistry and chemical engineering. Updated June 30 2019 In chemistry an atomic mass unit or AMU is a physical constant equal to one-twelfth of the mass of an unbound atom of carbon -12. The definition was adopted in November 2018 as one of the seven SI base units revising the previous definition that specified one mole as the amount of substance in 12.
Mol is the unit of measurement for amount of substance in the International System of Units SI. When a process occurs at constant pressure the heat evolved either released or absorbed is equal to the change in enthalpy. ORGANIC CHEMISTRY Organic chemistry involves the study of the structure properties and preparation of chemical compounds that consist primarily of carbon and hydrogen.
