Answer 5

Alright for Ao2, there are 16 moles of CO2 forming for every 2 moles of C8H18 reacting. So there's 8 times more CO2 than C8H18. So the answer is 3.5*8.

For a23, you have the same problem. There is 9 times more H2O forming than C8H18 reacting (18/2). So there should be a 9 in front of the H2O. The rest is fine.

Answer 6

Thanks. The picture for Ao2 is out of date, I fixed that problem. The equation says that there's 2C8H18 and 18H2O. Shouldn't that be the proper ratio?

Answer 7

Yes, that's the better way of doing it, you're right. It would give the same answer though of course.

Answer 8

So, 70.9704628 mL is the correct result?

Answer 9

No! You're writing it like 18 moles of H2O are forming for every mole of C8H18. It should be 9

Answer 10

Sorry I thought you were talking about something else in my last comment.

Answer 11

It's 18 mol of H2O for every 2 mol C8H18, so it's equivalent to 9/1 right?

Answer 13

Yes, sorry I missed your reply somehow!

Answer 14

18/2=9/1
