3. Two different compounds are formed by the elements carbon and oxygen. The first compound contains 42.9% by mass carbon and 57.1% by mass oxygen. The second compound contains 27.3% by mass carbon and 72.7% by mass oxygen. Show that the data are consistent with the law of multiple proportions.​

Respuesta :

The simplest whole number ratio of percentage of elements will be same according to law of multiple proportions.

Compound -1

  • Carbon=42.9%
  • Oxygen=57.1%

ratio:-

[tex]\\ \sf\longmapsto \dfrac{57.1}{42.9}=1.33[/tex]

Compound-2

  • Carbon=27.3%
  • Oxygen=72.7%

ratio

[tex]\\ \sf\longmapsto \dfrac{72.7}{27.3}=2.66[/tex]

Now compound ratio:-

[tex]\\ \sf\longmapsto \dfrac{2.66}{1.33}=2[/tex]

Hence verified
