Consider the following reaction sequence in which \(J, K, L\) and \(M\) are the major products.
Given:
Atomic mass (in amu): H : \(1\), C : \(12\), N : \(14\), O : \(16\), S : \(32\), Br : \(80\), Ba : \(137\)
The volume of \(1\,\text{M}\) aqueous \(\text{H}_2\text{SO}_4\) required to completely neutralize the ammonia evolved from \(5.72\,\text{g}\) of \(L\) in Kjeldahl’s method of nitrogen estimation is _____ mL.
Show Hint
Remember that Kjeldahl's method is not applicable to compounds containing nitrogen in nitro groups, azo groups, or ring systems (like pyridine), as these do not convert to ammonium sulfate under standard digestion conditions. Always check the functional groups before calculating the estimable nitrogen.
