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:-

0.2 gm of an organic compound was analysed by kjeldahl's method the ammonia evolved was absorbed in 60 ml (N)/(5)H_2SO_4 . Unused acid required 40 ml of (N)/(10)NaOH for complete neutralisation. Find the percentage of nitrogen in the compound.

0.50 gm of an organic compound was treated according to Kjeldahl's meghod. The ammonia evolved was absorbed in 50 ml of 0.5 MH_2SO_4 . The residual acid required 60 ml of (M)/(2)NaOH solution. Find the percentage of nitrogen in the compound.

A sample of 1.0 gm of organic compound was treated with NaOH and NH_(3) evolved was absorbed in 70ml 0.5M H_(2)SO_(4) . The residual acid required 65 ml of 0.5MNaOH solution of neutraization in Kjeldahl's method. What is the percentage of nitrogen is organic compound.
