For this reaction: C3H8 + 5 O2 =3 CO2 + 4 H2O, if you had 3 moles of C3H8 and 6 moles of O2, what would your limiting reactant be?

C3H8 would be your limiting reactant.

Explanation:

The limiting reactant in a reaction is the substance you have the least of. It ends, or limits, the reaction when it runs out.
