Final answer:
The volume of a 285g piece of gold with a density of 17.3 g/cm³ is calculated using the formula V = m / d, which yields approximately 16.47 cm³.
Step-by-step explanation:
To find the volume of a 285g piece of gold with a density of 17.3 g/cm³, you can use the formula for density, where density (d) = mass (m) / volume (V). Rearranging the formula to solve for volume gives us V = m / d. Plugging in the values we have V = 285g / 17.3 g/cm³. When you calculate this, you get the volume V ≈ 16.47 cm³.
Therefore, the correct answer is: b) 16.47 cm³.
