ANSWER:Step 1 of 8
Here, we are going to calculate the molecular mass or formula mass in amu of each of the molecule.
The molecular mass or formula mass is defined as the sum of the atomic masses (in amu) of each atom multiplied by the number of atoms of that element in the molecular formula in the molecule.
