# How many moles of water are produced in this reaction? 2 C8H18 (g) + 25 O2 (g) ---> 16 CO2 (g) + 18 H2O (g)

You have 18 formula moles but without further info, such as moles/mass of reactants, nothing more can be said about this problem.

This is the full updated and secure version to file explorer need to find online and save your folder to need searching file explorer windows 10 that the supported for process the best work thanks.

we can use the mole ratios here.

0.390 moles Octane x (25 moles O2 / 2 moles Octane) = 4.9 moles O2 ( needed)

0.63 moles O2 x ( 2 moles octane / 25 moles O2) = 0.0504 moles octane needed

Use amount of O2

0.63 moles O2 x (18 moles H2O / 25 moles O2)

= 0.4536 moles H2O

==> 0.4536 moles H2O produced. <==

I thought this ans would be above quation....but I gave one link that would be very useful .

No, it did not answer the question. How did you expect to get product moles without reactant moles/grams to drive the reaction?
