Chapter 1, Problem 1.25P

Interpretation Introduction

Interpretation:

Percentage error has to be calculated if the melting point of substance is found as $\text{128}\text{.7°C}$ and the value from reference is $\text{129}\text{.5°C}$.

Concept Introduction:

Accuracy can be measured using percentage error.  Percentage error is the difference between the average experimental values and/or true value, divided by true value, multiplied by $100$.  This can be represented in form of equation as shown below.

    $\text{Percentage}\text{error}=\frac{\text{average}\text{value}-\text{true}\text{value}}{\text{true}\text{value}}\times 100$
