The nitrogen content of organic compounds can be determined by the Dumas method. The compound in question is first passed over hot Cuo(s): Hot CuO(s)' Compound N2(g) + CO2(g) + H20(g) The gaseous products are then passed through a concentrated aqueous KOH solution to remove the CO2. The remaining gas contains N, and water vapor. A 0.143-g sample of a compound was treated as above, producing 89.1 mL of N2 saturated with water vapor at 25 °C and 761.5 torr. What is the mass percent of nitrogen in the compound? (The vapor pressure of water at 25 °C is 23.8 torr.)
