In Kjeldahl's estimation of nitrogen, the ammonia evolved from 0.5g of an organic compound neutralised 10ml of `1M H_(2)SO_(4)`. Calculate the percentage of nitrogen in the compound

Explanation

10mL pf `1M H_(2)SO_(4)` = 20mL of `1M NH_(3)`
1000mL of 1M ammonia contains 14g nitrogen
20mL of 1M ammonia contains `(14 xx 20)/(1000) g N_(2)`
Percentage of nitrogen `=(14 xx 20 xx 100)/(1000 xx 0.5) = 56.0`
