The following data were obtained from experiments to find the molecular formula of procaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 3.54 g sample of procaine with excess O2 formed 8.58 g CO2 and 2.70 g H2O . Another sample of mass 2.35g of procaine was found to contain 0.279 g of N. The molar mass of procaine was found to be 236. Find the molar formula of procaine.
