D => 0.055 moles

Explanation:

The molecular weight of O_2 can be calculated by adding up the masses in the compound.

2* 16.00 u (mass O-atom) =32.00 g/mol

Now to get the number of moles out of the mass given, you only have to divide the grams by the molecular weight!

1.75/32.00 =0,0546875 moles

This is answer D!
