Chapter 3.4, Problem 27SSC

Interpretation Introduction

Interpretation:

The type of compounds that are compared in the law of multiple proportions should be described.

Concept introduction:

The compound is made up of two or more than two elements in the same proportions by mass. A chemical compound is always made up of the fixed same proportion of elements by mass.

Answer to Problem 27SSC

When the different compound is composed of the same elements, the law of multiple proportions applies.

Explanation of Solution

According to the law of multiple proportions, the compositions of $\text{2}$ compounds composed of the same elements.

The compound composed of elements just like carbon monoxide is composed of 1 mole of carbon and 1 mole of oxygen. Same as the carbon dioxide is composed of one mole of carbon and two moles of oxygen so in both compounds the elements are the same but the masses of both elements combine in a fixed whole number.

Conclusion

By the law of multiple proportions, the many compounds are formed in a fixed whole number ratio. This helps for determining the compound composition by mass.
