The protein content of a sample was determined by a Kjeldahl analysis fornitrogen. After digesting a o.9814 g sample, the nitrogen content is oxidized toNH4+, converted to NH3 with NaOH, and the NH3 distilled into a collection flaskcontain 50.0o mL of o.1047 M HCl. The excess HCl is back titrated with o.1183 MNaOH, requiring 22.84 mL. What is the %w/w protein in the sample, given thatthere is 6.38 g of protein for every gram of nitrogen in the sample.

The question is based on the concept of quantitative analysis. We quantitatively estimate the…
