Answer:
Therefore, the correct answer is D) 5.0 x 10^-24 moles
Step by step solved :
To determine the number of moles of silicon in 3.01 x 10^24 atoms, we need to use Avogadro's number, which is the number of atoms in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23 atoms per mole.
Therefore, the number of moles of silicon in 3.01 x 10^24 atoms is:
(3.01 x 10^24 atoms) / (6.022 x 10^23 atoms/mole) = 5 moles
