Assuming the molar mass of oxygen is 18.01, you only need 16 grams (B) of oxygen because the molar mass of hydrogen is about 1 gram.
16+1+1=18

<h3>
Explanation:</h3>
<u>Step 1: Define</u>
[RxN] 2AlF₃ + 3K₂O → 6KF + Al₂O₃
[Given] 15.524 g KF
<u>Step 2: Identify Conversions</u>
[RxN] 2 mol AlF₃ = 6 mol KF
Molar Mass of Al - 26.98 g/mol
Molar Mass of F - 19.00 g/mol
Molar Mass of K - 39.10 g/mol
Molar Mass of AlF₃ - 26.98 + 3(19.00) = 83.98 g/mol
Molar Mass of KF - 39.10 + 19.00 = 58.10 g/mol
<u>Step 3: Stoichiometry</u>
- Set up:

- Multiply/Divide:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 5 sig figs.</em>
7.47966 g AlF₃ ≈ 7.4797 g AlF₃
