What is the density of a billiard ball that has a volume of 100 cm3 and a mass of 250 g? _______ g/cm3

To find the density of an object, you can use the formula: \[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \] In this case, the mass of the billiard ball is 250 g and the volume is 100 cm³. Plugging in these values: \[ \text{Density} = \frac{250 \, \text{g}}{100 \, \text{cm}^3} = 2.5 \, \text{g/cm}^3 \] Therefore, the density of the billiard ball is \( \mathbf{2.5 \, g/cm^3} \).
