Its mass is about 1/1836 of the mass of a hydrogen atom. The actual mass of the electron is 9.1085 × 10 −28 g or 9.1093 × 10 −31 kg. The mass of the electron is often ignored because this mass is too small. Electrons always provide a negative charge. WebMolecular mass or molar mass are used in stoichiometry calculations in chemistry. In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses.
