How many moles are contained in 3.131 * 1024 particles?

A. 5.199 mol

B. 18.85 mol

C. 0.5199 * 1023 mol

D. 1.885 * 1047 mol

All are wrong, it would be 5.324e-21 moles

Given:

The number of particles = 3.131 * 10²⁴

To determine:

The number of moles corresponding to the given particles

Explanation:

1 mole corresponds to Avogadro's number of particles = 6.023 * 10²³ particles

Therefore, the given particles would correspond to:

3.131 * 10²⁴ particles * 1 moles/6.023 * 10²³ particles = 5.199 moles

Ans: A) 5.199 moles are contained in 3.131 * 10²⁴ particles
