Answer: The amount of water produced is 18 moles.
Explanation:
The given chemical reaction follows:
\(2C_8H_{18}(g)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)\)
By Stoichiometry of the reaction:
2 moles of octane gas reacts with 25 moles of oxygen gas to produce 16 moles of carbon dioxide gas and 18 moles of water molecule.
Number of water molecules produced = 18 moles
Hence, the amount of water produced is 18 moles.
