We are asked to find the molecular weight of Oxygen. 

Molecular weight is simply the weight or mass of 1 mole of a molecule.  It is equal to the molar massgiven by the equation.  

Molecular weight = Molar Mass = atomic mass × # of atoms (subscript) in the molecule 

Recall that oxygen is diatomic, which means that it exists as O2 instead of O.  It is considered a molecule because it is composed of 2 elemental Oxygens
