According to the following reaction: C3H8 (g) + 5O2 (g) 3CO2 (g) + 4H2O (g) What would you multiply "moles of propane (C3H8)" by to convert to the units "moles of water" ?

Answer 1

One would use the unit factor method for this Organic combustion reaction and multiply moles of C3H8 by the stoichiometric mole ratio conversion factor of 4 moles H2O/1 mole C3H8 assembled from the balanced equation.
