31. A sample of meat scrap weighing 2.000 g is digested with concentrated H2SO4 and a catalyat. The resulting solution is made alkaline with NaOH and the liberated ammonia distilled into a 50.0 mL of 0.6700 N H2SO4. The excess  then requires 30.10 mL of 0.06520 N NaOH for neutralization. What is the percentage of nitrogen in the meat?
