Differentiate between Atomic and Molecular Masses.

1.	Differentiate between Atomic and Molecular Masses.
Answer» Atomic and Molecular Masses: Atomic Mass: Mass of an atom compared with one-twelfth mass of 1 atom of C₁₂ isotope taken as 12u. Molecular Mass: Mass of a molecule of covalent compound compared with one-twelfth mass of 1 atom of C₁₂ isotope taken as 12 u. It is equal to the sum of atomic masses of all the elements present in the molecule. Formula Unit Mass Mass of a molecule of an ionic compound It is also equal to the sum of atomic masses of all the elements present in the molecule.

Answer»

Atomic and Molecular Masses:

Atomic Mass: Mass of an atom compared with one-twelfth mass of 1 atom of C₁₂ isotope taken as 12u.

Molecular Mass: Mass of a molecule of covalent compound compared with one-twelfth mass of 1 atom of C₁₂ isotope taken as 12 u.

It is equal to the sum of atomic masses of all the elements present in the molecule.

Formula Unit Mass

Mass of a molecule of an ionic compound

It is also equal to the sum of atomic masses of all the elements present in the molecule.
