The nitrogen content of organic compounds can be determined by the Dumas method. The compound in question
Question:
The nitrogen content of organic compounds can be determined by the Dumas method. The compound in question is first reacted by passage over hot CuO(s):
The gaseous products are then passed through a concentrated solution of KOH to remove the CO2. After passage through the KOH solution, the gas contains N2 and is saturated with water vapor. In a given experiment, a 0.253- g sample of a compound produced 31.8 mL of N2 saturated with water vapor at 25oC and 726 torr. What is the mass percent of nitrogen in the compound? (The vapor pressure of water at 25oC is 23.8 torr.)
