6 Na, 2 P, 8 O. You simply need to muliple two to the original number of atoms which is 3Na,1P, and 4 0.

2Na3PO4
This expression says that you have two molecules of
Na3PO4. You know this because the number of atoms follows the element symbol, and the number of molecules comes at the beginning.
So, for 1 molecule of Na3PO4, you have
Na = 3 atoms
P = 1 atoms
O = 4 atoms
But, since you have 2 molecules, the final answer is
Na = 6 atoms
P = 2 atoms
O = 8 atoms
