From the balanced chemical equation, we can see that 3 moles of oxygen are required to react with 1 mole of propane (C3H8).
Therefore, to calculate how many moles of oxygen are needed to react completely with 7.97 moles of propane, we set up a proportion:
3 moles O2 / 1 mole C3H8 = x moles O2 / 7.97 moles C3H8
x = (3 moles O2 / 1 mole C3H8) * 7.97 moles C3H8
x = 23.91 moles O2
So, 23.91 moles of oxygen are necessary to react completely with 7.97 moles of propane.
Using this equation: C3H8 + 302 - 3C02 + 4H2
How many moles of oxygen are necessary to react completely with 7.97 moles of propane (C3H8)?
