In any pure sample of CO2, the ratio of the mass of carbon to the mass of
oxygen is always the same. You can justify this ratio by the fact that
compounds are composed of which of the following?
A. Identical molecules created from atoms combined in whole
number ratios
B. Atoms whose chemical properties do not change during a
chemical reaction
O C. Atoms whose masses do not change during a chemical reaction
D. Different molecules which together produce the observed
elemental ratios

Identical molecules created from atoms combined in whole number ratios this is the best justification for In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same.

What ratio of Mass of Oxygen and Carbon?

Consider the elements carbon and oxygen. Combined in one way, they form the familiar compound carbon dioxide. In every sample of carbon dioxide, there are 32.0g of oxygen present for every 12.0g of carbon. By dividing 32.0 by 12.0, this simplifies to a mass ratio of oxygen to carbon of 2.66 to 1.
Carbon has an atomic weight of 12, oxygen in diatomic form(O2) of 32 and CO2 of 44. This means that the mass of 6x1023 atoms of CARBON has a mass of 6 kilograms, the mass of 6x1023 diatomic oxygen molecules is 32 kg, and for CO2 it is 44kg. So carbon is the lightest and CO2 the heaviest.
