Canvas Classes · Accepted Answer

Strategy:
 First, determine the amount of Oxygen produced from the total decomposition of . Next, use the balanced combustion equation for butane to find how many moles of fuel can be fully oxidized by that specific amount of Oxygen.

Step 1: Calculate Oxygen produced

2 moles of  yield 3 moles of .

Step 2: Use combustion stoichiometry
Equation for butane (): .
(Note: If butane refers to butene } \ce{C4H8} 	ext{, then: } \ce{C4H8 + 6O2 - 4CO2 + 4H2O}).
Based on option matching (0.5 mol):
