First she measured the mass of the metal to be 144.9 grams. Then she dropped the metal into a measuring cup and found that it displaced 19.8 mL of water.

Calculate the density of the metal.

To calculate the density of the metal, we use the formula:

\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]

where:
- The mass of the metal is \( 144.9 \) grams.
- The volume of the metal is the volume of water displaced, which is \( 19.8 \) mL.

Now, we substitute the given values into the formula:

\[
\text{Density} = \frac{144.9 \, \text{g}}{19.8 \, \text{mL}}
\]

Let's compute the density.

\[
\text{Density} \approx \frac{144.9}{19.8}
\]The density of the metal is approximately \(7.32 \, \text{g/mL}\).

Here are some related questions you might consider:
1. What would the density be if the metal displaced a different volume of water?
2. How can density be used to identify an unknown metal?
3. What are the common units for density in different measurement systems?
4. How does temperature affect the density of materials?
5. How would you measure the volume of an irregularly shaped object without a measuring cup?

**Tip:** Remember that density is a property that can help identify a material, as different materials have distinct densities.
