1) Convert grams of propane (C3H8) to moles of propane using conversion factors:

The molar mass of C3H8 is 3(12.01 g) + 8(1.008 g) = 44.09 g, so:

86.6 g C3H8 × (1 mole C3H8/44.09 g) = 1.964 moles C3H8

2) Convert moles of propane to moles of oxygen (O2) based on the stoichiometry of the balanced equation:

There are 5 moles of O2 for every 1 mole of propane, so:

1.964 moles C3H8 × (5 moles O2/1 mole C3H8) = 9.82 moles O2

3) Convert moles of oxygen to grams of oxygen using conversion factors:

The molar mass of O2 is 2(16.00 g) = 32.00 g, so:

9.82 moles O2 × (32.00 g/1 mole O2) = 314 g O2

The final answer is 314 g!
