What is the molar mass of an oxygen molecule, O_(2) A. 8.0g/mol B. 16.0g/mol C. 32.0g/mol D. 6.02times 10^23g/mol A B D

The molar mass of an oxygen molecule, $O_{2}$, is the sum of the molar masses of the two oxygen atoms it contains. The molar mass of a single oxygen atom is approximately $16.0g/mol$. Therefore, the molar mass of an oxygen molecule, $O_{2}$, is $2 \times 16.0g/mol = 32.0g/mol$.<br /><br />So, the correct answer is:<br />C. $32.0g/mol$
