Q. 2.84 - An Introduction to General, Organic, and Biological Chemistry

Question

Measure the length of each of the objects in diagrams (a), (b). and (c) using the metric ruler in the figure. Indicate the number of significant figures for each and the estimated digit for each. (2.2)

Step-by-Step Solution

Answer

The number of significant figures for each scale and the estimated digit for each is determined as $2$

Introduction

The given is the picture of objects with scales having measurements

The objective is to determine the number of significant figures and the estimated digit

Step 1

(a) The object's length is $3.8 cm$;

The total number of significant figures is two, 

and the total number of estimated digits is two as well.

Step 2

(b) The object's length is $2.5 cm$. 

The number of significant figures is two dollars.

$2$ is also the number of estimated digits.

Step 3

(c) The object's length $=4.1 cm$

 the number of major figures in dollars $=2$

Number of estimated digits in  $=2$
