What is the difference between molar mass and Gram molecular mass?
In the International System of Units (SI), the coherent unit of molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol. The mole was defined in such a way that the molar mass of a compound, in g/mol, is numerically equal to the average mass of one molecule or formula unit, in daltons.

Jul 29, 2021 · The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.
The molar mass is the mass of one mole of substance, whether the substance is an element or a compound. A mole of substance is equal to Avogadro's number (6.023×10 23 ) of that substance. The molar mass has units of g/mol or kg/mol.
May 10, 2023 · The molar mass of an element is equal to its atomic mass in atomic mass units (\text{amu}) converted to grams per mole. For example, the molar mass of carbon is 12.01\text{ g/mol} , which is the atomic mass of carbon ( 12.01\text{ amu} ) converted to grams per mole.
Jul 22, 2022 · The concept that allows us to bridge these two scales is molar mass. Molar mass is defined as the mass in grams of one mole of a substance. The units of molar mass are grams per mole, abbreviated as g/mol.
Aug 17, 2022 · First, molecular mass is either unitless or else reported in daltons (Da) or atomic mass units (amu or u). On the other hand, the unit for molar mass is grams per mole (g/mol) or kilograms per mole (kg/mol). Second, molecular mass describes the mass of a single molecule or type of molecule.
