Count the number of TOTAL number of atoms in each compound listed below.
Na2(SO4)2
a.16 total atoms
b.12 total atoms
c.4 total atoms
d.7 total atoms
e.3 total atoms
f.15 total atoms
The correct answer is f. 15 total atoms.
In Na2(SO4)2, there are 2 sodium atoms (2 Na), 1 sulfur atom (1 S), and 8 oxygen atoms (4 O). Therefore, the total number of atoms is 2 + 1 + 8 = 15.
