In Kjeldahl's method, the gas evolved from 1.325g sample of fertilizer is passed into 50.0 mL of 0.2030N `H_(2)SO_(4)`. 25.32 mL of 0.1980 N NaOH are required for percentage of nitrogen in fertilizer ?

In Kjeldahl's method, the gas evolved from 1.325 g sample of a fertiliser is passed into 50 ml of 0.2030 N H_2 SO_4 .25.32 ml of 0.1980 N NaOH are required for the titration of unused acid. Calculate the percentage of nitrogen in the fertiliser.

During the estimation of nitrogen in an organic compound by Kjeldhal's method, the ammonia evolved from 0.5g of the compound was absorbed in 50 ml of 0.5 M H_(2)SO_(4) . The residual acid required 60 ml of 0.5 M NaOH solution. The percentage of nitrogen in the compound is

0.303 g of an organic compound was analysed for nitrogen by Kjeldahl's method. The ammonia evolved was absorbed in 50 ml of 0.1 N H_2 SO_4 . The excess acid required 25 ml of 0.1 N NaOH for neutralisation. Calculate the percentage of nitrogen in the compound.

In the Kjeldahl's method for estimation of nitrogen in a soil sample, ammonia evolved from 0.75 g of sample neutralised 10 ml of 1 M H_(2) SO_(4) . The percentage of nitrogen in the soil is
