Chapter 2: Q.2.75 (page 51)

In an old trunk, you find a piece of metal that you think may be aluminum, silver, or lead. You take it to a lab, where you find it has a mass of 217 g and a volume of 19.2 cm3. Using Table 2.8, what is the metal you found?

Short Answer

Expert verified

The metal is Lead and the value of density is 11.3 g/cm3.

Step by step solution

01

Given Information

Mass of metal =217 g

Volume of metal = 19.2 cm3

02

Explanation

Density is defined as the ratio of mass over volume. Every substance has a unique density, which distinguishes it from others. It is given by:

Density=massofsubstancevolumeofsubstance

On substituting the values:

Densityofmetal=217g19.2cm3Densityofmetal=11.3g/cm3

1g/cm3=1g/mL

While looking at the table,

The metal is Lead.
