4HF (aq) + SiO2 (s) → SiF4 (g) + 2H₂O(1) A chemist needs to know what mass (in grams) of silicon dioxide is needed to produce 18.0 mol of water. Below is part of the work. Solve this problem on your own first before completing this question. 18.0 mol H₂O 1 X al a2 a3 1 mol SiO₂ =? g SiO₂ Match each part with where it belongs in the set-up for the stoichiometry calculation. One the answers is not needed, so match that answer with "This is not needed".
