We’re being asked to calculate the mass of octane (C8H18) consumed by the reaction of 8.5 g O2


For this problem, we need to do the following steps:

Step 1: Write and balance a chemical equation for the given reaction.

Step 2: Calculate the mass of C8H18 consumed.



Step 1: From the problem, the given reaction is:

C8H18 + O2 → CO2 + H2O


This equation is not yet balanced. To balance it, we have to make sure that the number of elements on both sides is equal.
