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. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu". Web25 de ago. de 2024 · So, the mass of a mole of the atom is ma × NA. But this quantity is in the unified mass unit (u). The above equation can convert u to g mol −1. Therefore, the average atomic mass divided by one unified mass unit times the molar mass constant results in the molar mass. The precise value of Mu is 0.999 999 999 65 (30) g mol −1.
