To start, let’s take into account an instance. Suppose we need to discover the molar mass of a molecule consisting of carbon (C) and oxygen (O). The chemical formulation of the compound is CO2. The atomic mass of carbon is 12.01 g/mol, and the atomic mass of oxygen is 16.00 g/mol.
To calculate the molar mass, we have to multiply the atomic mass of every factor by the variety of atoms current within the molecule. Since there may be one carbon atom and two oxygen atoms within the molecule, the molar mass will be calculated as follows:
Molar mass of CO2 = (12.01 g/mol) x 1 (carbon atom) + (16.00 g/mol) x 2 (oxygen atoms)
Molar mass of CO2 = 12.01 g/mol + 32.00 g/mol
