Here's how to figure out the number of atoms in sodium acetate (NaC₂H₃O₂):

1. Identify the elements:

* Sodium (Na)

* Carbon (C)

* Hydrogen (H)

* Oxygen (O)

2. Count the number of atoms of each element:

* Sodium (Na): 1 atom

* Carbon (C): 2 atoms

* Hydrogen (H): 3 atoms

* Oxygen (O): 2 atoms

3. Total the number of atoms:

1 + 2 + 3 + 2 = 8 atoms

Therefore, there are 8 atoms in one molecule of sodium acetate.
