Answer to Question #290724 in Organic Chemistry for Enya

Question

A sample of meat scrap weighing 2.000 g is digested with concentrated sulfuric acid and a catalyst. The resulting solution is made alkaline with NaOH and the liberated ammonia distilled into 50.00 mL of 0.6700 N HCl. The excess acid then requires 30.10 mL of 0.6520 N NaOH for neutralization. What is the percentage of the protein in the meat? The Kjeldahl factor is 6.25.

Answer 1

Protein. Meat — such as beef — is mainly composed of protein. The protein content of lean, cooked beef is about 26–27% ( 2 ). Animal protein is usually of high quality, containing all nine essential amino acids needed for the growth and maintenance of your body ( 3 ).
