Verified step by step guidance1
Identify the chemical formula given: SO_3, which consists of sulfur (S) and oxygen (O) atoms.
Determine the number of oxygen atoms in the molecule, which is 3 in this case.
Recall the naming convention for molecular compounds composed of nonmetals: use prefixes to indicate the number of atoms (mono-, di-, tri-, etc.) and the element names.
Since there is one sulfur atom and three oxygen atoms, the correct prefix for three is 'tri-', and the suffix for oxygen changes to '-oxide'.
Combine the element name and prefix to form the name: 'Sulfur trioxide'.
