A 1.013-g sample of tuna was analyzed by the Kjeldahl method. The ammonia formed was distilled into a 75.00-mL 0.02139 M H₂SO₄ solution. A 5.21 mL back-titration of 0.05324 M NaOH was required. (Note the stoichiometry of your acid and base) QUESTION. a) What is the % N (14.007 g/mol) of the tuna sample? b) If fish in general has 5.71 g protein per g N, what is the % protein of the sample?
