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.

The following data were obtained from experiments to find the molecular formula of an unknown compound which acts as a common local anesthetic. The unknown compound contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 4.82 g sample of the unknown compound with excess oxygen formed 12.67 g of carbon dioxide and 4.076 g of water. Another sample of the unknown compound with a mass of 1.12 g was found to contain 0.1339 g of nitrogen. The molar...
