Please explain to me the difference of molecular weight in g/mol versus dalton
Molecular weight, expressed in both grams per mole (g/mol) and daltons (Da), is a measurement that quantifies the mass of a specific molecule. The molecular weight is determined by the sum of the atomic weights of all the atoms present in the molecule.
The unit g/mol represents the molecular weight in terms of grams per mole. This unit is derived from the molar mass, which is the mass of a substance divided by its amount in moles. For example, if you have 1 mole of a substance that weighs 10 grams, the molecular weight would be 10 g/mol
On the other hand, the dalton (Da) is another unit used to express molecular weight. It is named after John Dalton, an English chemist who developed the atomic theory. The dalton is defined as one-twelfth the mass of an atom of carbon-12, which is approximately equal to 1. 66 x 10^-24 grams
The relationship between g/mol and daltons is straightforward. One gram/mole is equal to 6. 022 x 10^23 daltons. This value (Avogadro’s number) represents the number of atoms or molecules in one mole of a substance
In summary, both g/mol and dalton are units used to quantify molecular weight. The g/mol unit provides the mass of a mole of molecules in grams, while dalton measures the mass of individual atoms or molecules in atomic mass units (AMU). The conversion factor between g/mol and dalton is Avogadro’s number (6. 022 x 10^23)
