Answer:
This is based on the masses of one element, that will be combined with a fixed mass of the other element.
Explanation:
This is based on the masses of one element, that will be combined with a fixed mass of the other element. Thoses masses are in a ratio.
This state we can find in 'The Law of Multiple Proportions, which is part of Dalton's atomic theory
We see that in the 2 compounds, the masses of oxygen, that combine with a fixed mass of carbon , will be in proportion.
For the first oxide we have 1g carbon per 1.33 g Carbon
1g /1.33g = 0.752
For the second oxide we have 1g carbon per 2.66g Carbon
1g/2.66g = 0.376
Dividing the mass O per g C of the second (larger value) compound:
2.66 / 1.33 = 2 which is the same as 0.752 / 0.376
thus, it means that the masses of oxygen that combine with carbon are in a 2:1 ratio.
