Chapter 2.4, Problem 2QQ

Interpretation Introduction

Interpretation:

The incorrect statement about significance of zeros in recorded measurement has to be chosen from the given options.

Concept Introduction:

Whenever a measurement is made, the significant figures in the measured quantity give the actual measurement.  For this the significant figures should be recognized first.  The significant figures may be non-zero digit and zero digit.  But Zero may be or may not be a significant figure.  It depends on where the zero appears.  Leading zeros in the front of any number are never significant.  Zeros between the numbers are significant.  Zeros appearing at the last (trailing zeros) are significant if a decimal point is there in the number.
