The following data were obtained from experiments to find the
molecular formula of lidocaine, a local anesthetic, which contains
only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of
a 3.54-g sample of lidocaine with excess O2 formed 9.32 g CO2 and
3.00 g H2O . Another sample of mass 2.35 g was found to contain
0.281 g of N . The molar mass of lidocaine was found to be 234.
Find the molar formula of lidocaine.
