To calculate the mass of a single copper atom, you need to use the given information provided in the question. We are given the mass of the copper sample as 63.5 grams and the Avogadro's number, which is 6.02x10^23 atoms/mole.

To solve the problem, follow these steps:

1. Convert the number of atoms to moles:
Divide the given number of atoms (6.02x10^23) by Avogadro's number:
6.02x10^23 atoms / (6.02x10^23 atoms/mole) = 1 mole

2. Calculate the molar mass of copper:
The molar mass of copper is the atomic mass of copper, which is 63.5 grams/mole. This value can be found on the periodic table.

3. Divide the mass of the sample by the number of moles:
63.5 grams / 1 mole = 63.5 grams/mole

4. Divide the molar mass by Avogadro's number:
63.5 grams/mole / (6.02x10^23 atoms/mole) ≈ 1.055x10^-22 grams/atom

Therefore, the mass of a single copper atom is approximately 1.055x10^-22 grams.
