How many moles produced during a reaction

Question

How many moles of H2O form when 6.70 mol of C3H8 completely reacts? Show each step.

Answer 1

Write the correctly balanced equation for the reaction:

C₃H₈ + 5O₂ ==> 3CO₂ + 4H₂O ... balanced equation

Use dimensional analysis:

6.70 mols C₃H₈ x 4 mol H₂O / 1 mol C₃H₈ = 26.8 mols H₂O
