Chapter 5.3, Problem 6RQ

Interpretation Introduction

Interpretation: Form the given values of density and mass, volume of the liquid needs to be determined.

Concept Introduction: The density is defined as the ratio of mass of an object to its volume:

  $\text{Density =}\frac{\text{mass}}{\text{volume}}$

Answer to Problem 6RQ

Volume of the liquid is $18.99\text{mL}$ .

Explanation of Solution

Given values are as follows:

  $\begin{array}{c}\text{Density}=0.79\text{g}/\text{ml}\\ \text{mass}=15.0\text{g}\\ \text{Volume}=?\end{array}$

Substitute above values in below equation.

  $\begin{array}{c}\text{Density =}\frac{\text{mass}}{\text{volume}}\\ \text{volume}=\frac{\text{mass}}{\text{density}}\\ =\frac{15.0\text{g}}{0.79\text{g}/\text{mL}}\\ =18.99\text{mL}\end{array}$

Hence, volume is $18.99\text{mL}$ .

Conclusion

Thus, volume of the liquid is $18.99\text{mL}$ .
