Chapter 5, Problem 24A

(a)

Interpretation Introduction

Interpretation: Significant figure of

1422 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(a)

Expert Solution

Answer to Problem 24A

Significant figure of 1422 is 4.

Explanation of Solution

All non-zero integers are count as significant figures. The number 1422 contains four nonzero integers. So, all of these are count as significant figure. Hence, significant figure of this number is 4 .

(b)

Interpretation Introduction

Interpretation: Significant figure of 65,321 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(b)

Expert Solution

Answer to Problem 24A

Significant figure of 65,321 is 5 .

Explanation of Solution

All non-zero integers are count as significant figures. The number 65,321 contains five nonzero integers. So, all of these are count as significant figure. Hence, significant figure of this number is 5 .

(c)

Interpretation Introduction

Interpretation: Significant figure of 1.004×105 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(c)

Expert Solution

Answer to Problem 24A

Significant figure of 1.004×105 is 4.

Explanation of Solution

All non-zero integers are count as significant figures. The number 1.004×105=100400 . There is no decimal symbol in the end of the number. So, this two zero are not count in significant figure. Hence, significant figure of this number is 4.

(d)

Interpretation Introduction

Interpretation: Significant figure of 200 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(d)

Expert Solution

Answer to Problem 24A

Significant figure of 200 is 1.

Explanation of Solution

The number 200 contains two zero at the right end of the number. There is no decimal symbol in the end of the number. So, this two zero are not count in significant figure. Hence, significant figure of this number is 1.

(e)

Interpretation Introduction

Interpretation: Significant figure of 200. needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figures in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(e)

Expert Solution

Answer to Problem 24A

Significant figure of 200. is 3.

Explanation of Solution

The number 200. contains two zero at the right end of the number and has decimal symbol in the end of the number. So, this two zero are count in significant figure. Hence, significant figure of this number is 3.

(f)

Interpretation Introduction

Interpretation: Significant figure of 2.00×102 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(f)

Expert Solution

Answer to Problem 24A

Significant figure of 2.00×102 is 3.

Explanation of Solution

The number 2.00×102 is written as 200. the number 200. contains two zero at the right end of the number and has decimal symbol in the end of the number. So, this two zero are count in significant figure. Hence, significant figure of this number is 3.

(g)

Interpretation Introduction

Interpretation: Significant figure of 435.662 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(g)

Expert Solution

Answer to Problem 24A

Significant figure of 435.662 is 6.

Explanation of Solution

All non-zero integers are count as significant figures. The number 435.662 contains six nonzero integers. So, all of these are count as significant figure. Hence, significant figure of this number is 6.

(h)

Interpretation Introduction

Interpretation: Significant figure of 56.341 needs to be explained.

Concept Introduction: Significant figure are exact digits which are known with certainty. Significant figure in a measurement is the number of figures which are known with certainty plus one that is uncertain with first non-zero digit.

(h)

Expert Solution

Answer to Problem 24A

Significant figure of 56.341 is 5.

Explanation of Solution

All non-zero integers are count as significant figures. The number 56.341 contains five nonzero integers. So, all of these are count as significant figure. Hence, significant figure of this number is 5.
