Answer :

To calculate the density of a rock, you can use the formula for density, which is: \[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \] Now, let's use the given values: - The mass of the rock is \( 15 \) grams. - The volume of the rock is \( 3 \) cubic centimeters (which is the same as \( 3 \) milliliters, since \( 1 \) cm³ is equivalent to \( 1 \) mL). Using these values in the density formula: \[ \text{Density} = \frac{15 \text{g}}{3 \text{cm}³} \] When we divide \( 15 \) grams by \( 3 \) cubic centimeters, we get: \[ \text{Density} = 5 \frac{\text{g}}{\text{cm}³} \] So the density of the rock is \( 5 \) grams per cubic centimeter.
