Question

Carbon and oxygen are known to form two compounds . The carbon compound is one of these is 42.9% while in the others it is 27.3% . Show that this data is in agreement with the law of multiple proportions.

Answer 1

Answer:-

In the first compound

• Carbon=42.9℅
• Oxygen=(100- 42.9)℅=57.1℅

In the second compound

• Carbon=27.3℅
• Oxygen=(100-27.3)℅=72.7℅

$\star$ In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen:-

$\\ \sf\longmapsto \dfrac{57.1}{42.9}=1.33Parts$

$\star$ In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen:-

$\\ \sf\longmapsto \dfrac{72.7}{27.3}=2.66Parts$

Ratio:-

$\\ \sf \longmapsto 1.33:2.66=1:2$

Since this ratio is a simple whole number ratio ,hence the given data illustrates the law of multiple proportions.
