molar mass is, gram atomic mass or gram Molecular mass of a compound.

Answer:
Explanation:
∆ 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.
∆ A mass in grams numerically equal to the molecular weight of a substance or the sum of all the atomic masses in its molecular formula. Gram atomic mass is the mass, in grams, of one mole of atoms in a monatomic chemical element.
∆ Moreover, the main difference between both is that molar mass gives the mass of a mole of a particular substance. Whereas molecular weight is the mass of a molecule of a particular substance. While the definition and units are different for molar mass and molecular weight, the value is the same.

Answer:
Explanation:
a mole of any substance has been redefined in the SI as the amount of that substance containing an exactly defined number of particles, N = 6.02214076×1023. Therefore, the molar mass of a compound now is simply the mass of this number of molecules of the compound.
