By using the Kjeldahl’s method,
%N = 37.33%
In the Kjeldahl’s method for estimation of nitrogen present in a soil sample, ammonia evolved from 0.75 gm of sample neutralized 10 mL of 1 M H2SO4, The percentage of nitrogen in the soil is;( Option A 37.33 )(Option B 45.33)( Option C 35.33)( Option D 43.33)
