Nitrogen content of an organic compound can be determined by the Dumas Method. The compound is passed over hot copper (II) oxide and reacts as follows: Compound N 2 + CO 2 + H 20The product gases are passed through a solution of potassium hydroxide to remove CO2. The remaining gas is N2 saturated with H20 vapour. In a given experiment 0.225g of the unknown compound produces 27.8mL of N2 saturated with H2O vapor at 25oC and 730Torr. What mass is the % of nitrogen in the compound? (NB: vapour pressure of H2O at this temperature is 23.8Torr.)
