The density of an object is equal to the mass of the object divided by the volume of the object. What is the volume, in milliliters, of an object with a mass of 24 grams and a density of 3 grams per milliliter?

Options

A. 0.125
B. 8
C. 21
D. 72

Explanation

To find the volume of an object given its mass and density, we can use the formula for density:

\[ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} \]

We need to rearrange this formula to solve for volume \( V \):

\[ V = \frac{m}{\rho} \]

### Step-by-step Solution:

1. **Identify the given values**:
- Mass \( m = 24 \) grams
- Density \( \rho = 3 \) grams per milliliter

2. **Substitute the values into the volume formula**:
\[ V = \frac{m}{\rho} = \frac{24 \text{ grams}}{3 \text{ grams/milliliter}} \]

3. **Perform the division**:
- First, cancel out the units (grams):
\[ V = \frac{24}{3} \text{ milliliters} \]

4. **Calculate the result**:
\[ V = 8 \text{ milliliters} \]

Thus, the volume of the object is **8 milliliters**.
