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.

Explanation

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%
