Chapter 5.2, Problem 3RQ

(a)

Interpretation Introduction

Interpretation: The significant zeros needs to be determined.

Concept Introduction: Measurement lies at the heart of doing science. Any measurement involves an estimate and thus is uncertain to some extent. A reliably identified digits used to find a decimal point is known as significant figure.

Answer to Problem 3RQ

The answer is $6$ .

Explanation of Solution

The number of meaningful digits in a calculated quantity is known as significant figures. All non- zero digits are significant and leading zeros are never count as significant but captive zeros are significant.

The given number is $100.010$ . According to the rules of significant figures, there are $6$ significant figures in the number $100.010$ .
