Well, we have to convert grams to moles. To do this, we need first find the atomic mass of oxygen. 1 mole of oxygen is 16 grams according to the atomic mass. Here is the rest:

Answer= 1.279g/mol
We know this because the molar mass of Oxygen is 16g
25/16 is 1.279
that gives us the answer for how many moles there are in the equation.
