1.	The ammonia evolved form 0.20 g of an organic compound by kjeldahl method neutralised 15ml of N // 20 Sulphuric acid solution. Calculate the percentage of Nitrogen.
Answer» Solution :WEIGHT of organic compound = 0.20 g VOLUME of sulphuric acid taken= 15 ml `"Strength of sulphuric acid taken" = (N)/(20)=0.05 N` `"Percentage of NITROGEN"=(14 xx NV)/(1000 xx 10) xx 100` `=(14 xx 0.05 xx 15)/(1000 xx 0.20) xx 100=(1050)/(200)=5.25%` `IMPLIES`% of nitrogen=5.25%
