| this may be simple, but this 2004 ap free response question, number 2:
A) determine the empirical formula of a hydrocarbon that contains 85.7% carbon by mass.
I can't figure this out, i know how to get to the answer, Carbon/(Carbon + Hydrogen) x 100...but I can't get 85.7% exact. And i think empirical means it has to be in it's lowest form or something.
can anyone help me out? |
