a-5-7650-gram-sample-of-beef-was-analyzed-for-its-mathrm-n-14-mathrm-g-mathrm-mol-pa971

A \( 5.7650 \) gram sample of beef was analyzed for its \( \mathrm{N}(14 \mathrm{~g} / \mathrm{mole}) \) content and the liberated \( \mathrm{NH}_{3} \) was collected in a \( 52.80 \mathrm{~mL} \) of \( 0.1793 \mathrm{M} \mathrm{HCl} \) and \( 4.39 \mathrm{~mL} \) back titration with \( 0.0118 \mathrm{M} \mathrm{NaOH} \) was required. Calculate the percentage protein in the beef sample. (Answers should be written in 2 decimals place and do not include the UNIT)

To solve this problem, we need to first determine the mass of nitrogen present in the beef sample. To do this, we can use the volume and concent
