The approximate atomic mass of lithium is 6.941 g/mol.
Understanding Atomic Mass
Atomic mass is a measure of the total mass of protons and neutrons in an atom's nucleus. It's typically measured in atomic mass units (amu) or grams per mole (g/mol). The atomic mass is essential for calculations in chemistry and physics. Lithium (Li) is an alkali metal, the third element on the periodic table, with an atomic number of 3.
