1. Density:
* The density of copper is approximately 8.96 g/cm³.
2. Molar Mass:
* The molar mass of copper is 63.55 g/mol.
3. Avogadro's Number:
* Avogadro's number is 6.022 x 10²³ atoms/mol.
Calculations:
* Mass of the cube: 1 cm³ * 8.96 g/cm³ = 8.96 g
* Moles of copper: 8.96 g / 63.55 g/mol = 0.141 mol
* Number of atoms: 0.141 mol * 6.022 x 10²³ atoms/mol ≈ 8.49 x 10²² atoms
Therefore, there are approximately 8.49 x 10²² copper atoms in a 1 cm³ cube of copper.
