Chemistry Problem!!!
« on: March 31, 2009, 07:41:09 AM »
Hi,

Can somebody explain how to answer this question????

What is the maximum amount of carbon monoxide that can be produced by reaction of 1 kg octane (C8H18) with 1 kg of oxygen to produce CO and H2O?

The answer is 1.956 kg

Thank you.

Start with the reaction equation. This is a limiting reagent problem.

Is this correct? ..C8H18 + 8.5O2 = 8CO + 9H20??

But i dont know were to go from here.

do you say 1 mole of octane +8.5 moles of oxygen produce 8 moles of CO?
