I have to solve this combustion problem using Dimensional Analysis and molar heat:

2 C2H6 +7O2 yields 4 CO2 + 6H2O + 3120 kJ

The question is to discover how much heat is produced along with 8 moles of water in this reaction.

My problem is that I have no idea how to go about solving this sort of problem. Is there a website with examples, or would you be able to show me step by step how to figure this out? Thank you so much for your help, I appreciate it.

    I took 8 moles and multiplied it by 3120 KJ and divided that by 6 moles to get 4160KJ

    My calculator shows 4160 kJ also.
