Chapter 2, Problem 66A

Interpretation Introduction

Interpretation:

The density of a $\text{5}\text{mL}$ water sample having mass of $\text{5}\text{g}$ needs to be determined.

Concept introduction:

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Answer to Problem 66A

Density of the given water sample is $1\text{g/mL}$.

Explanation of Solution

Mass of the water sample = $5\text{g}$

Volume of the water sample = $\text{5}\text{mL}$

The density of the water sample can be calculated by dividing the mass by volume.

$\begin{array}{c}\text{Density}=\frac{\text{Mass}}{\text{Volume}}\\ =\frac{5\text{g}}{\text{5}\text{mL}}\\ =1\text{g/mL}\end{array}$

Hence, the density of water sample is $1\text{g/mL}$.

Conclusion

Thus, the density of the given water sample is $1\text{g/mL}$.
