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 mass of the unknown compound was found to be 234 g/mol. Find the molecular formula of the unknown compound.
