Given the following unbalanced equation: C3H8 + O2 → CO2 + H2O

If you want to make 13.60 moles of H2O, how many moles of C3H8 do you need?

3.400 mol C₃H₈

Explanation:

Step 1: Write the balanced equation

C₃H₈ +  5 O₂ →  3 CO₂ +  4 H₂O

Step 2: Establish the appropriate molar ratio

The molar ratio of C₃H₈ to H₂O is 1:4.

Step 3: Determine the moles of C₃H₈ needed to produce 13.60 moles of H₂O

We will use the previously established molar ratio.

13.60 mol H₂O × 1 mol C₃H₈/4 mol H₂O = 3.400 mol C₃H₈
