Hydrogen sulfide gas burns in oxygen to produce sulfur dioxide and water vapor.

what mass of oxygen gas is consumed in a reaction that produces 2 mol SO2?

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.
