Find the percentage of nitrogen in an organic compound analysed by Kjeldahl method. 1.61g of the compound produced `NH_(3)` which was absorbed in 250 mL of `(N)/(2) H_(2)SO_(4)` solution. The remaining acid was then diluted to one litre, 25mL of which required 25.5mL of N/10 NaOH for exact neutralization.

0.1gm of organic compound was analysed by Kjeldahl's method,In analysis produced NH_(3) absorbed in 30mlN/5H_(2)SO_(4) .The remaining acid required 20mlN/10NaOH for neutralisation.Calculate percentage of nitrogen in organic compound:-

1.216 gm of an organic compound was reacted under Kjeldahl's method and the ammonia evolved was absorbed in 100 ml NH_2SO_4 . The remaining acid solution was made up to 500 ml by the addition of water. Twenty millilitres of the dilute solution required 32 ml (N)/(10) caustic soda solution for complete neutralisation. Calculate the percentage of nitrogen in the compound.

A samlpe of 0.5 of an organic compound was analysed using Kjeldahl' method. The ammonia evolved was absorbed in 50 ml of 0.5 M H_(2)SO_(4) . The unsused acid after neutralisation by ammonia consumed 80 ml of 0.5N NaOH. Then calculate percentage of nitrogen in organic compound
