Hint: To solve this question, we should know about the concept of atoms. Molar mass is the mass of the one mole of the compound whereas atomic mass is the mass of the individual unit of the compound. Basically, molar mass is the mass of an average of many elements of the compound and atomic mass is the mass of the atom.
Complete answer:
For example, let us take hydrogen chloride .
The atomic mass of can be calculating by using atomic masses of the individual elements found on the periodic table:
This is equivalent to the molar mass of , that is:
So, the atomic mass of the compound is , and the molar mass is .
Note:
We should ensure not to be confused between the two terms, atomic mass and atomic weight. Atomic mass is the mass of an atom whereas atomic weight is the weight of the average of the naturally occurring isotopes.
Complete answer:
Molar mass | Atomic mass |
The molar mass of the compound is defined as the total mass of atoms in grams present in a mole of a molecule. | On the other hand, atomic mass is termed as the mass of the atom. |
In other words, it is the mass of one mole of the compound or Avogadro number of particles, i.e. | It can also be defined as the number of protons and the number of neutrons. |
The molar mass is the average of many samples of the compound which often vary in mass because of the presence of isotopes. The S.I. The unit of molar mass is | The S.I. The unit of atomic mass is amu , which is defined as |
For example, let us take hydrogen chloride
The atomic mass of

This is equivalent to the molar mass of

So, the atomic mass of the compound
Note:
We should ensure not to be confused between the two terms, atomic mass and atomic weight. Atomic mass is the mass of an atom whereas atomic weight is the weight of the average of the naturally occurring isotopes.
