Carbon and oxygen to form carbon
Chemical properties include reactivity with other elements of substances, toxicity, flammability, and chemical stability
just to name a few
(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.
