Question
What is the final weighed/titrated species of nitrogen in the Dumas method compared to Kjeldahl's method?
Answer: B
💡 Solution & Explanation
Dumas relies on elementally converting all nitrogen to free $N_2$ gas for volumetric measurement. Kjeldahl converts nitrogen chemically to $NH_3$ for acid-base titration.
