Understanding Moles in Atoms: A High School Chemistry Question

How many moles are in 6.13 × 10²⁴ atoms of lead?

A. 0.525 moles

B. 5.25 moles

C. 10.18 moles

D. 52.5 moles

E. 1.52 moles

Final Answer:

The number of moles in 6.13 × 10²⁴ atoms of lead is 10.18, answer choice C.

The subject of this question is chemistry and it falls within the scope of high school academics. It is asking about the concept of moles, specifically, how many moles are in 6.13 × 10²⁴ atoms of lead.

The answer to the question can be found using Avogadro's number, which is 6.02×10²³ mol⁻¹ and it states that one mole always contains this amount of atoms, regardless of the element. Therefore, to find the number of moles in 6.13 × 10²⁴ atoms of lead, you need to divide the total number of atoms of lead (6.13 × 10²⁴) by Avogadro's number (6.02 × 10²³ mol⁻¹).

Doing this, you get approximately 10.18 moles. Hence, the answer to the question is C. 10.18 moles.

Understanding the concept of moles in atoms is crucial in chemistry as it helps in calculating the amount of substance in chemical reactions and understanding the composition of matter on a microscopic level.
