Question

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)

Answer 1

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
