Practice Exam 3 - PDF solutions error for #8

[Zellmer, Robert]

There's an error in the solutions for #8.

The question asks for the molecular formula.  The solution stops at the empirical formula,
C13H18O2.  This has an empirical formula wt of 206 amu.  It gives the molar mass as
412 g/mol (MW = 412 amu).  Divide 412 by 206 you get 2.  So, the molecular formula is
C26H36O4.

The Carmen video version is correct.
