Answer:
191g of water.
Explanation:
For the reaction:
SiO₂(s) + 4HF(g) → SiF₄(g) + 2H₂O(l) ΔH°rxn = -184 kJ
Two moles of water are formed and the reaction produce 184 kJ of energy. To produce 975 kJ of energy:
975 kJ energy × = 10,6 moles of H₂O
Using molar mass of water (18,02 g/mol), mass of H₂O must form when 975 kJ of energy are produced is:
10,6 moles of H₂O× = <em>191 g of water</em>
I hope it helps!
