Question

Differentiate between

1 Atomic mass
2 Gram Atomic Mass
3 Molecular Mass
4 Gram Molecular Mass​

Answer 1

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

Answer 2

1) Atomic mass - A property closely related to an atom's mass number is its atomic number . The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu . By definition , an atom of carbon with six neutrons , carbon-12 , has an atomic mass of 12 amu .

2) gram atomic mass - The quantity of an element whose mass expressed is gram in numerically equal to it atomic mass is known as gram atomic mass .

3) Molecular mass- The sum of the atomic masses of all atoms in a molecule, based on a scale in which the atomic masses hydrogen , carbon, nitrogen and oxygen are 1, 12, 14 and 16 respectively . for ecample - the molecular mass of water which has two atoms of hydrogen and one atom of oxygen, is 18 ( i.e. ,2+16) .

4) gram molecular mass - Gram molecular mass is equal to the molecular weight of a substance or the sum of all atomic masses in its molecular formula . It is equal to molecular mass of a molecule in grams .
