Final answer:
A molecule of sodium acetate (NaC2H3O2) contains 8 atoms. Using Avogadro's number, 1 mole of sodium acetate contains 4.8176 × 10²24 atoms.
Step-by-step explanation:
To calculate the number of atoms in a compound, we need to first interpret the chemical formula correctly. The compound NaC2H3O2 is sodium acetate. The molecular formula for acetate (C2H3O2) tells us there are 2 carbon (C) atoms, 3 hydrogen (H) atoms, and 2 oxygen (O) atoms. Including the sodium (Na) atom, there are a total of 8 atoms in a single molecule of sodium acetate.
Using Avogadro's number, NA = 6.02 × 10²23 particles/mole, we can determine the number of atoms in a mole of sodium acetate.
Each mole of sodium acetate will contain 8 moles of atoms because each molecule has 8 atoms.
Therefore, 1 mole of sodium acetate contains 4.8176 × 10²24 atoms
(4.8176 × 10²24 atoms = 8 atoms/molecule × 6.02 × 10²23 molecules/mole).
