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