Question

What is the difference between gram atomic mass and gram molecular mass also what is the difference between unified mass and gram molecular mass.

Answer 1

1. Gram atomic mass is the mass, in grams, of one mole of atoms in a monatomic chemical element, In short, it is same as the atomic mass in grams, for example , GAM of O is 16g
2.GRAM molecular is same as GAM just the difference of the word " molecule".it is equal to molecular mass in grams for exmaple - GMM of H2O is 18g
Note that both these terms are same as the molar mass.
3. unified mass(u) or atomic mass unit(amu) or Dalton (da) is the unit of measurement of molecular or atomic masses. 1 u= 1.66×10^-27 Kg

hope this helps

Answer 2

Answer:

When atomic mass is defined in terms of gram it is known as gram atomic mass.

When molecular mass is defined in terms of gram it is known as gram molecular mass.

ExplanationAtomic weight if oxygen is 16amu. 1 mole of oxygen is 6.02×10^23 therefore 1 amu =1.661×10^-24gram.

Molecular mass in gram is equal to atomic weight of the atom.
