Combustion analysis was performed on an anesthetic containing only C, H, N and O. Complete combustion of a 3.54 g sample of this anesthetic with excess oxygen gas formed 8.49 g of carbon dioxide and 2.14 g of gaseous water. Another 2.35 g sample of the anesthetic was found to contain 0.199 g of N.(Hint: Use this information to find the nitrogen content in the combustion sample!) The molar mass of the anesthetic was found to be 165 g/mol. Find...
