Carbon and oxygen forms two compounds. Carbon content in one of them is while in
Carbon and oxygen forms two compounds. Carbon content in one of them is \( 42.9 \% \) while in the other is 27.3\%. The given data is in support with:
- A. Law of definite proportions
- B. Law of reciprocal proportions
- C. Law of multiple proportion
- D. Law of conservation of mass
Step-by-step solution
In compound 1, carbon is 42.9% and oxygen is 57.1%. The mass of oxygen per gram of carbon is 57.1/42.9 ≈ 1.331. In compound 2, carbon is 27.3% and oxygen is 72.7%, so oxygen per gram of carbon is 72.7/27.3 ≈ 2.663. The ratio of the masses of oxygen combining with a fixed mass of carbon is 2.663/1.331 ≈ 2, a small whole number, illustrating the law of multiple proportions.
