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 mass, given by the equation.
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.
