One mole of oxygen molecules contains more independent units (O2) than one mole of oxygen atoms (O).
A) True, because there are two atoms of O for every molecule of O2.
B) True, because one mole of O2 weighs more than one mole of O.
C) False, because both of them have the same number of particles.
D) False, because one mole of O has the same mass as one mole of O2.
