Chemistry unit 3.2
WebSince 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which are assigned masses of exactly 12 amu. (This isotope is known as “carbon-12” as will be discussed later in this module.) Thus, one amu is exactly 1 12 of the mass of one carbon-12 atom: 1 amu = 1.6605 × 10 −24 g.
