Question

C3H8 + 3O2 → 3CO2 + 4H2

How many moles of oxygen are necessary to react completely with 6.3 moles of propane (C3H8)?

Answer 1

From the balanced chemical equation, we see that 1 mole of propane reacts with 3 moles of oxygen. Therefore, to react completely with 6.3 moles of propane, we need:

3/1 x 6.3 = 18.9 moles of oxygen.

So, 18.9 moles of oxygen are necessary to react completely with 6.3 moles of propane.
