You have 4.872 x 10^34 atoms of copper. how many moles is this? a. 7.666 x 10^32 mol b. 2.933 x 10^58 mol c. 1.237 mol d. 8.093 x 10^10 mol

D. 8.090 × 10¹⁰

Step-by-step explanation:

Use Avogadro’s number to convert atoms of Cu to moles of Cu.

1 mol Cu atoms = 6.022 × 10²³ atoms of Cu

      Moles of Cu = 4.872× 10³⁴ × 1 /6.022 × 10²³

      Moles of Cu = 8.090 × 10¹⁰ mol Cu

Thee are 8.090 × 10¹⁰ mol Cu in 4.872× 10³⁴ atoms of Cu.
