Chapter 1, Problem 31A

Interpretation Introduction

Interpretation:

Number of molecules that could be formed from 6, 9 and 27 oxygen particles needs to be determined, if three oxygen particles are needed to form ozone.

Concept introduction:

Ozone is a substance made up of oxygen and is present in the atmosphere responsible for absorbing some of the harmful radiations before they reach earth’s surface. It is located in the stratosphere.

Answer to Problem 31A

6 oxygen molecules $=2ozonemolecules$

9 oxygen molecules $=3ozonemolecules$

27 oxygen molecules $=9ozonemolecules$

Explanation of Solution

3 oxygen molecules form 1 molecule of ozone. Thus, the ratio of oxygen to ozone is 3:1. So when the number of oxygen molecules is 6, then two ozone molecules will be formed. When the number of oxygen molecules is 9, then 3 ozone molecules will be formed and when the number of oxygen molecules is 27, then 9 ozone molecules is formed.

Conclusion

Thus,

6 oxygen molecules $=2ozonemolecules$

9 oxygen molecules $=3ozonemolecules$

27 oxygen molecules $=9ozonemolecules$
