Question

what is gram atom why this concept is used in chemistry​

Answer 1

Answer:

For timepass they have not get anything so they used it

Answer 2

The quantity of an element whose weight in grams is numerically equal to the atomic weight of the element is called Gram Atom.

The term gram-atom (abbreviated gat) has been used for a related but distinct concept,

namely a quantity of a substance that contains Avogadro's number of atoms,

whether isolated or combined in molecules.

Thus,

for example, 1 mole of MgB2 is 1 gram-molecule of MgB2 but 3 gram-atoms of MgB2.
