Solution:

Kjeldahl's method is simpler and more
convenient than Duma's method. This method is
largely used for the estimation of nitrogen in food
stuff, drugs, fertilisers and many other organic
compounds. However, this method cannot be used
for organic compounds containing nitrogen in the
ring such as pyridine, quinoline and organic
compounds containing nitro (-N) and
diazo (-N = N-) groups.
