Final answer:
To find the volume of copper given its mass and density, divide the mass (65.55 g) by the density (8.9 g/cm³), resulting in a volume of approximately 7.37 cm³.
Step-by-step explanation:
The student has asked how to find the volume of a substance given its mass and density. The formula to calculate volume (V) is V = mass (m) / density (ρ). Given that copper has a density of 8.9 g/cm³ and a mass of 65.55 g, the volume can be calculated by dividing the mass by the density.
Here's the calculation step-by-step:
- Write down the known values: density of copper (ρ) = 8.9 g/cm³ and mass (m) = 65.55 g.
- Apply the formula for volume: V = m / ρ.
- Calculate the volume: V = 65.55 g / 8.9 g/cm³ = 7.36629 cm³.
Therefore, the volume of the copper is approximately 7.37 cm³ (rounded to two decimal places).
