To calculate the density of the ball, you can use the formula for density:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
Given:
- Mass = 404.2 g
- Volume = 500.0 cm³
Now, substituting the values into the formula:
\[ \text{Density} = \frac{404.2 , \text{g}}{500.0 , \text{cm}^3} = 0.8084 , \text{g/cm}^3 \]
Now, rounding this to the nearest ten-thousandth:
\[ \text{Density} = 0.8084 , \text{g/cm}^3 \]
Thus, the most accurate calculation of density for the ball is 0.8084 g/cm³.
