Question
A new penny has a mass of $2.49 \mathrm{g}$ and a volume of 0.349 $\mathrm{cm}^{3} .$ Is the penny pure copper?
Step 1
The density of an object is calculated by dividing its mass by its volume. In this case, the mass of the penny is 2.49 g and the volume is 0.349 cm³. \[Density = \frac{Mass}{Volume} = \frac{2.49g}{0.349cm^3}\] Show more…
