If you have 2.41 * 1024 atoms of copper, how many moles of copper do you have? If you have 2.41 atoms of copper, how many moles of copper do you have? 4.00 0.600 3.00 0.250 none of the above

4.00 moles

Explanation:

Avogadro's number is 6.022 x 10²³ molecules, atoms, particles, etc.

Here we are talking of atoms of copper, so 1 mol of copper is equal to 6.022 x 10²³ atoms, and we only need to setup the proportion to find the number of mol in 2.41 x 10²⁴ atoms. (Think of it like a dozen, avogadro's is 6.022 x 10²³)

(1 mol copper / 6.022 x 10²³ atoms of copper) x 2.41 x 10²⁴ atoms

= 4.00 moles
