Question

define mole and gram atomic mass.​

Answer 1

Answer:

Other units. g/mol. In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×1023 particles, expressed in grams.

Mole :- A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Gram atomic mass :- Gram atomic mass(weight) of an element is the mass of Avogadro number ( 6.023 x 1023 ) of atoms of that elements in grams.” Ex – mass of 1 atom of oxygen = 16 amu = 16 x 1.66 x 10-24 gm. Mass of 6.023 x 1023 atoms of oxygen= 16 x 6.023 x 1023 x 1.66 x 10-24 = 16 gm. Hence, Gram atomic weight of oxygen = 16 gm.
