Answer :
There are approximately 30.48 moles of copper in a 6.00 cm x 6.00 cm x 6.00 cm cube of copper. To calculate the number of moles in a 6.00 cm x 6.00 cm x 6.00 cm cube of copper, you'll need to follow these steps.
1. Find the volume of the cube: 6.00 cm x 6.00 cm x 6.00 cm = 216 cm³
2. Convert the volume to liters: 1 cm³ = 0.001 L, so 216 cm³ = 0.216 L
3. Calculate the mass of copper in the cube using its density. The density of copper is 8.96 g/cm³, so:
Mass = Volume x Density = 216 cm³ x 8.96 g/cm³ = 1936.96 g
4. Finally, calculate the number of moles using copper's molar mass, which is 63.55 g/mol:
Moles = Mass / Molar Mass = 1936.96 g / 63.55 g/mol = 30.48 moles
There are approximately 30.48 moles of copper in a 6.00 cm x 6.00 cm x 6.00 cm cube of copper.
