Final answer:

To convert 5.00 g of copper to moles, divide the mass of copper by its molar mass (63.54 g/mol). The resulting value is approximately 0.0787 moles of copper.

Step-by-step explanation:

To convert grams of copper to moles of copper, we can use the atomic mass of copper and Avogadro's number. The atomic mass of copper (Cu) is approximately 63.54 g/mol. Avogadro's number is 6.022 × 10²³ atoms/mol. The number of moles is found by dividing the mass of the substance by its molar mass.

If we have 5.00 g of copper, the calculation will look like this:

  • Mass of copper = 5.00 g
  • Molar mass of copper = 63.54 g/mol

Number of moles of copper = Mass of copper / Molar mass of copper

Number of moles of copper = 5.00 g / 63.54 g/mol = 0.0787 mol

Therefore, 5.00 g of copper is equivalent to approximately 0.0787 moles of copper.
