0.3 g of an organic compound on Kjeldahl's analysis gave enough ammonia to just neutralise 30 mL of 0.IN H_(2)SO_(4) . Calculate the percentage of nitrogen in the compound.

1.	0.3 g of an organic compound on Kjeldahl's analysis gave enough ammonia to just neutralise 30 mL of 0.IN H_(2)SO_(4) . Calculate the percentage of nitrogen in the compound.
Answer» Solution :Weight of organic compound (w) = 0.3 g Strength of SULPHURIC acid used (N) = 0.1 N Volume of sulphuric acid used (V) = 30 ML 30 ml of 0.1 N sulphuric acid = 30 ml of 0.1 N ammonia `:. "Percentage of nitrogen" =((14 xx NV)/(1000 xx w)) xx 100=((14 xx 0.1 xx 30)/(1000 xx 0.3)) xx 100=14%`
