Question

Define molar mass house different from molecular mass explain with help of an example​

Answer 1

Answer :

First, you will need the mass of individual compounds. This number is found under the element on the period table. For example, the molecular weight of oxygen is 16.00 amu.

Once you know the mass of the individual components of a compound, you can find the molecular weight.

For example, the molecular weight of water (H2O) is:

The mass of hydrogen is 1.008 amu, and the mass of oxygen is 16.00 amu. Plugging that in yields:

Adding the molecular weights of each element together gives:

Thus, the molecular weight of water is 18.02 amu.

Answer 2

Molar mass:

• This is of the mass of substance and this is in the SI unit. SI unit in the form of g/mol. Molar mass is also known as Mass of Avogadro number of atoms or Moleculer weight.

Example to prove this is in the form of g/mol:

• Suppose, If mass of 1 mole of any atom is 1.27282 gram (approx) the the molar mass would we 1.27282 g/mol.

Molecular mass:

• In molar mass its of the mass of substance, here moleculer mass is refered to be mass of molecule hence its said to be molecular mass. This is measured in the form of amu.

Example:

• AMI => atomic mass of unit, number of atoms in a molecule is considered as AMU.

• Suppose if a molecule has 4 atoms such as: 2 atoms and 1 hydrogen, then the amount of Atomicity would be (2 + 1) = 3 Amu.
