Final answer:
The theoretical density of copper is already provided as 8.95 g/cm³, which is calculated based on the mass of a mole of copper atoms and Avogadro's number. No further calculation is required.
Step-by-step explanation:
To calculate the theoretical density of copper, we can use the given mass of one mole of copper atoms and Avogadro's number. The density (ρ) of copper is given as 8.95 g/cm³.
Using Avogadro's number, we can determine the number of atoms in one mole, which is 6.02 × 10²³ atoms/mol. With the mass of one mole of copper being approximately 63.5 g, we calculate the number of atoms per cm³.
The calculation would involve converting grams to kilograms and cm³ to m³, then using the formula ρ = mass/volume to find the density of copper in kg/m³. However, since we are provided with the density of copper already, additional calculations are not required to answer the question directly. The theoretical density of copper, as provided, is 8.95 g/cm³.
