Explanation:</h3>
<u>Step 1: Define</u>
[RxN} FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
[Given] 2.43306 g FeCl₃
<u>Step 2: Identify Conversions</u>
[RxN] 1 mol FeCl₃ = 3 mol NaCl
Molar Mass of Fe - 55.85 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of Na - 22.99 g/mol
Molar Mass of FeCl₃ = 55.85 + 3(35.45) = 162.2 g/mol
Molar Mass of NaCl - 22.99 + 35.45 = 58.44 g/mol
<u>Step 3: Stoichiometry</u>
- Set up:
- Multiply/Divide:
<u>Step 4: Check</u>
