Multiple proportions

Question

When carbon is oxidized in a small amount of oxygen, the principle product formed is carbon monoxide (CO ). When the oxidation occurs in a higher concentration of oxygen, the principle product formed is carbon dioxide (CO2 ). The mass ratio of oxygen to carbon in carbon dioxide (CO2 ) is twice the mass ratio of oxygen to carbon in carbon monoxide (CO ).

 

Identify the statements that are correct.
Check all that apply.
 
The mass ratio of oxygen to carbon in CO is twice the mass ratio of oxygen to carbon in CO2 .

For two compounds of C and O , the mass ratio of C to O in one compound is a multiple of the mass ratio of C to O in the other compound.

The mass ratio of oxygen to carbon in CO is 1.33 for every sample of CO .

The mass ratio of oxygen to carbon in CO2 is 2.667 for every sample of CO2 .

Answer 1

Assuming that the compounds are made from the same isotopic distribution of carbon and oxygen, all answers are true.

12/16 = 2(12/32)

16/12 = 1.33

32/12 = 2.67
