Explanation:

If I asked how many atoms there were in a dozen formula units of

B

a

C

l

2

, I think you would quickly answer 3 dozen: 12 barium atoms, and 24 chlorine atoms.

The question specified molar quantities, and the mole is just another number, admittedly a very large number, i.e.

N

A

=

6.022
