Kjeldahl question for Analytical Chemistry?
Can you please double check my answer I got for this question..
The kjeldahl procedure for nitrogen analysis was used on a 0.9325g sample of wheat flour. The NH3 produced was collected in an excess of 4.0% boric acid. The resulting ammonium borate complex required 33.15 ml of 0.1124 M HCl for titration to the end point. What is the weight percent of nitrogen in wheat flour? Use the appropriate factor to find the %protien in the flour. The answer I found is 5.59% can someone double check for me please? The answer I got is 5.59%. Thanks!
