(1) According to the chemical formula of plasticizer, one molecule of plasticizer consists of 24 carbon atoms, 34 hydrogen atoms and 4 oxygen atoms, so one molecule of plasticizer contains 62 molecules.
(2) The relative molecular weight of plasticizer is12× 24+1× 34+16× 4 = 386.
(3) The mass ratio of carbon, hydrogen and oxygen in plasticizer is (12× 24): (1× 34): (16× 4) =144:17: 32.
