Question

How many moles of Silicon is 3.01 X 10^24 Atoms?

A.2.24 X 10^-24 Moles
B. 1.8 X 10^-24 Moles
C.3.01 X 10^-24 Moles
D. 5.0 X 10^-24 Moles

Answer 1

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
