Lithium average atomic mass
Web9 sep. 2024 · Lithium (Li) has two stable isotopes Li-6 and Li-7. Lithium's (Li) atomic mass is is 7.0 u. So in this case, the mass of isotope Li-6 times it's relative abundance (x) plus the average of the mass of isotope Li-7 times it's relative abundance (y) = lithium's atomic number: 6.0151 (x) + 7.0160 (y)= 7.0 Since there are only two isotopes, x + y= … The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. The protons and neutrons of the nucleus account for nearly all of the total mass of at…

A commercial source of lithium, … WebLithium has a mean atomic mass of 6.94 amu. This number indicates that lithium-7 is much more common than lithium-6 because it is so close to the atomic weight of lithium-7 (7.02 amu). The amount of each isotope is taken into account when calculating an element's average atomic mass. Lithium has an atomic mass that is 6.94 amu on average.
