Question

If you are given two moles of a substance, which of the following would be correct?
You have the same number of particles as in 12 grams of carbon-12.
You have one-third the number of particles that are in 12 grams of carbon-12.
You have two times the number of particles that are in 12 grams of carbon-12.
You have one half the number of particles that are in 12 grams of carbong-12.

Answer 1

Answer:

C. You have two times the number of particles that are in 12 grams of carbon-12.

Explanation:

Avogadro's number, 6.022 ×10^23, equals the number of particles in 12 grams of carbon-12.

This mean 1 mole of a substance will equals to the number of particles that are in 12 grams of carbon-12.

Therefore, 2 moles of a substance will equals to two times the number of particles that are in 12 grams of carbon-12.
