Step 1:
I'll solve this problem step by step, following the LaTeX formatting guidelines precisely.

Step 2:
: Identify the Elements

The chemical formula is $$O_{2}$$, which means we need to find the molar mass of oxygen.

Step 3:
: Determine the Atomic Mass of Oxygen

From the periodic table, the atomic mass of oxygen is $$16.00 \mathrm{g/mol}$$.

Step 4:
: Calculate the Molar Mass

Since the molecule is $$O_{2}$$, we multiply the atomic mass by 2:
\mathrm{Molar~Mass} = 16.00 \mathrm{g/mol} \times 2 = 32.00 \mathrm{g/mol}

Final Answer

Key Insights: - Molar mass is calculated by summing the atomic masses of all atoms in a molecule - For diatomic molecules like O_{2}, multiply the atomic mass by the number of atoms
