Answer:
96.0 grams of oxygen gas (O2) will be produced.
Option B is correct.
Explanation:
Step 1: Data given
Number of moles SO2 = 2.0 moles
Molar mass O2 = 32.0 g/mol
Step 2: The balanced equation
2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(g)
Step 3: Calculate moles oxygen gas (O2)
For 2 moles H2S we need 3 moles O2 to produce 2 moles SO2 and 2 moles H2O
For 2.0 moles SO2 produced we need 3/2 * 2.0 = 3.0 moles O2
Step 4: Calculate mass O2
Mass O2 = moles O2 * molar mass O2
Mass O2 = 3.0 moles * 32.0 g/mol
Mass O2 = 96.0 grams
96.0 grams of oxygen gas (O2) will be produced.
Option B is correct.
