How many atoms are there in 2 moles of sodium?

A. 6.02 * 10^23 atoms

B. 1.2 * 10^24 atoms

C. 3.32 * 10^24 atoms

D. 2.4 * 10^25 atoms

(NOT A OR D)

B.

One mole of any element or compound contains 6.02x10^23 particles (atoms or molecules)

One mole of a compound has 6.02x10^23 molecules

One mole of an element has 6.02x10^23 atoms

Therefore, 2 moles would have the double of 6.02x10^23 atoms
