Chemistry - PLEASE CONFIRM ANSWER.
Please check this answer closely. Unless I have goofed, and I have been known to do that, this is a limiting reagent problem and you have not determined the limiting reagent. I think O2 is the limiting reagent; thus, your answer is too high by a factor of almost 2.
