Solution

Formula Mass:
“The total of the atomic weights of the atoms in the empirical formula of a chemical is the formula mass (also known as formula weight).”
Sulfur dioxide:
Sulfur dioxide is also known as sulfurous acid anhydride, sulfurous anhydride, or sulfur oxide and has the chemical formula ${SO}_{2}$ .
Sulfur dioxide contains both sulfur ( $S$ ) and oxygen ( $O$ ).
The molecule sulfur dioxide ( ${SO}_{2}$ ) is made up of one sulfur atom and two oxygen atoms.
Formula Mass of Sulfur Dioxide
The molar mass of sulfur is $32.1 g {mol}^{- 1}$
The molar mass of oxygen is $16.0 g {mol}^{- 1}$
$Formula mass = [1 \times 32.1] [2 \times 16]$
$= 32.1 \times 32$
$= 64.1 g {mol}^{- 1}$
Hence, the formula mass for sulfur dioxide is $64.1 g {mol}^{- 1}$ .
