For CO 2 (m.w. = 44.01 u), mole CO 2 = 44.01 g CO 2 = 6.022 x 10 23 CO 2 molecules. Because each CO 2 molecule is composed of one carbon atom and two oxygen atoms, we could say that a mole of CO 2 contains one mole of carbon atoms and two moles of oxygen atoms. In general, it is useful to think of a mole as just an Avogadro's number of things.
