Question: how to find the empirical formula of c2h2?
Answer: also called the simplest formula, gives the simplest whole number ratio of atoms of each element present in a compound Exp The simplest ratio for acetylene (C2H2) is 1:1. The empirical formula for acetylene is CH. For benzene (C6H6) the simplest ration is also 1:1, so the empirical formula for benzene is also CH.
