<p>Dr. Pounds,</p>
<p>I was doing your chapter 11 additional problems. On number
10, it is asking us to write the molecular formula, but I got
a little confused. Hydrocarbon consists of a hydrogen and a
carbon, BUT it doesn't give us a percentage for carbon, so how
did you get the 83.63 on the answer sheet for carbon? </p>
<p> </p>
<p> </p>
<p>Thank you</p>

You are correct -- it is just hydrogen and carbon. So if 16.37%
hydrogen, the rest (83.63%) has to be carbon.<br>
