Question

the molar mass in grams is numerically not equal to- • atomic mass • formula mass •molecular mass •1 mole​

Answer 1

Answer:

The mole was defined in such a way that the molar mass of a compound, in g/mol, is numerically equal (for all practical purposes) to the average mass of one molecule, in daltons. Thus, for example, the average mass of a molecule of water is about 18.0153 daltons, and the molar mass of water is about 18.0153 g/mol
