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.

A 10.0 ml of (NH_(4))_(2) SO_(4) solution was treated with excess of NaOH . The ammonia evolved was absorbed in 50 ml of 0.1 N HCl. The excess HCl required 20 ml of 0.1 N. NaOH . Calculate the strength of (NH_(4))_(2) SO_(4) in the solution.

Some amount of NH_4 CI was boiled with 50ml of 0.75 N NaOH solution till the reaction was complete. After the completion of the reaction 10 ml of 0.75 N H_2 SO_4 was required for the neutralization of the remaining NaOH . The amount of NH_4 CI taken was:
