Question

Which of the following is equal to the number of particles in 36 grams of carbon-12?

B. 3 moles
A. 3:1 molar mass
C. 3:1 mole ratio
D. 1:3 molar volume

Answer 1

The quick answer is B

3 moles

A mole has an alternate definition of 6.02 * 10^23 particles or atoms (in this case) that make it up.

A is possible, but it is not the question.

C is possible, but it is not the question.

I've never directly seen D before. It is used with gases (indirectly).

Answer 2

The answer is B

3 moles
