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

C3H8 + 5 O2 → 3 CO2 + 4 H2O
(13.60 mol H2O) x (1 mol C3H8 / 4 mol H2O) = 3.400 mol C3H8

The coefficient of H2O must be 4 times the coefficient of C3H8,
as the hydrogens appear only in those two terms.
To get 13.60 moles of H2O, you need 3.40 moles of C3H8.
