We're being asked to determine which statement is correct about the complete combustion of 3.00 mole of propane, C3H8.

We're given the following balanced reaction.

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g)


Let's calculate the amount of CO2(g) and H2O(g) produced from 3.00 mol C3H8(g).

moles C3H8 (mole-to-mole comparison) → moles CO2
