2.6 g of an element X is reacted with an aqueous solution containing NaOH and `NaNO_(3)` to yield `Na_(2)XO_(2) " and "NH_(3)` .`NH_(3)` thus liberated is absorbed in 100mL of 0.11 M `H_(2)SO_(4)` . The excess acid required 48 mL of 0.25 M NaOH for complete neutralisation. Find the atomic weight of X.

2.0 g of an elements is reacted with aqueous solution containing KOH and KNO_(3) to yield K_(2)XO_(2) and NH_(3).NH_(3) thus liberated is absorbed in 200 " mL of " 0.05 M H_(2)SO_(4) . The excess acid required 10 " mL of " 1.5 M NaOH for complete neutralisation Which of the following statements is/are correct?

________ ml of 0.1 M H_(2)SO_(4) is required to neutralise 50 ml of 0.2 M NaOH solution

0.303 g fo sample was analysed for nitrogen by Kjeldahl's method. The ammonia gas evolved was absorbed in 50 ml of 0.05 M H_(2)SO_(4) . The excess acid required 25 ml of 0.1 M NaOH for neutralisation.

……………. ml of 0.1 M H_(2)SO_(4) is required to neutralize 50 ml of 0.2 M NaOH Solution :

100ml of 0.2 M H_(2)SO_(4) is added to 100 ml of 0.2 M NaOH . The resulting solution will be
