Explanation:</h3>
<u>Step 1: Define</u>
[RxN - Balanced] Fe₃O₄ + 4H₂ → 3Fe + 4H₂O
[Given] 705.0 g H₂O
<u>Step 2: Identify Conversions</u>
[RxN] 4 mol H₂O → 1 mol Fe₃O₄
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Fe - 55.85 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
Molar Mass of Fe₃O₄ - 3(55.85) + 4(16.00) = 231.55 g/mol
<u>Step 3: Convert</u>

2264.74 g Fe₃O₄ ≈ 2265 g Fe₃O₄
Answer:
Explanation:
Hello,
At first, the moles of magnesium sulfate must be computed by knowing that its molecular mass has a value of 120.366 g/mol:
Now, by knowing that the volume must be in L, it turns out into 0.10000 L, thus:
Best regards.
