Given the reaction: C3H8(g) + 5O2(g) �¨ 3CO2(g) + 4H2O(g)

What is the total volume of H2O(g) formed when 8.00 liters of C3H8(g) is completely oxidized?

1 answer

When dealing with gases one may dispense with changing everything to moles. Volumes are proportional.
8 L C3H8 x ((4 moles H2O/1 mole C3H8) = 8 x (4/1) = ??
