Chapter 9, Problem 116A

Interpretation Introduction

Interpretation: The density of the substance is to be calculated.

Concept Introduction : Density is the ratio of the mass of the substance to the volume. It is different for different substances. The concept of density is used to predict whether the given sample floats or sinks into another sample.

Answer to Problem 116A

The density is $0.5{\text{g/cm}}^{\text{3}}$ .

Explanation of Solution

Given:

• Mass is 6.62 g
• Volume is 12.3 ${\text{cm}}^{\text{3}}$

The density is calculated as follows:

  $\begin{array}{c}\text{Density}=\frac{\text{Mass}}{\text{Volume}}\\ =\frac{6.62\text{g}}{\text{12}{\text{.3 cm}}^{\text{3}}}\\ =0.5{\text{g/cm}}^{\text{3}}\end{array}$

Thus, the density is $0.5{\text{g/cm}}^{\text{3}}$ .
