Question

the chart shows the density of several metals.

metal	density (g/cm³)
copper	8.95
gold	19.3
iron	7.87
lead	11.3
magnesium	1.74
silver	10.5
tin	7.26

a sample of each metal is collected that is 1 cm³. which sample would have the greatest mass?
a gold
b iron
c lead

Explanation:

Step1: Recall density - mass - volume formula

The formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. When $V = 1\ cm^{3}$, then $m=
ho\times V=
ho$.

Step2: Compare densities

We compare the densities of the metals given: Aluminum ($2.70\ g/cm^{3}$), Copper ($8.95\ g/cm^{3}$), Gold ($19.3\ g/cm^{3}$), Iron ($7.87\ g/cm^{3}$), Lead ($11.3\ g/cm^{3}$), Magnesium ($1.74\ g/cm^{3}$), Silver ($10.5\ g/cm^{3}$), Tin ($7.26\ g/cm^{3}$). Gold has the highest density among them.

Answer:

A. Gold
