Question

Carbon and oxygen combine to form two oxides, carbon monoxide and carbon dioxide in which the ratio of the weight of carbon and oxygen is respectively 12:16 and 12:32. These figures illustrate the :

Answer 1

These ratios are calculated on the basis of atomic mass .

since carbon has atomic mass=12 and oxygen has atomic mass=16

therefore in CO2(carbon dioxide) atomic mass = 12:32
whereas in CO (carbon monoxide) atomic mass=12:16
