Answer:
15 grams of carbon dioxide
Explanation:
You would just add 68+7 and that gives you 75. Next subtract 75-68 and that gives you 15.
(3 grams of carbon) x (1 mole of carbon/12 grams ) =3/12 = 1/4 of a mole of carbon. Then... ( 1/4 of a mole) x (6.02 x 10^23 atoms/mole) = approximately 1.5 x 10^23 atoms.
