Chapter U1.5, Problem 6E

Interpretation Introduction

Interpretation:

Density of a piece of metal with given volume and mass must be found out. Also, the unknown metal needs to be identified.

Concept introduction:

Density of a substance is the ratio of mass to the volume.

Thus,

$d=\frac{m}{V}$

Here, m is mass and V is volume.

Answer to Problem 6E

Density of the metal is 8.4 g/cm³.

The metal could be Copper.

Explanation of Solution

From given mass and volume, density can be calculated as follows:

$d=\frac{m}{V}$

Since, it is given that mass is 252 g and volume is 30.0 cm³.

Putting the values,

$d=\frac{252\text{ g}}{30{\text{ cm}}^{\text{3}}}=8.4{\text{ g/cm}}^{\text{3}}\text{.}$

Conclusion

Thus, the density of the given metal is 8.4 g/cm³.

The metal corresponding to the given density is 8.4 g/cm³.
