A typical protein contains 16.2 wt% nitrogen (N). A 0.500 mL sample of protein solution was decomposed, and the liberated ammonia (NH3) was reacted with 10.00 mL of 0.02140 M HCl.
NH3 + HCL = NH4Cl
The unreacted HCl required 3.26 mL of 0.0198 M NaOH for complete titration. Find the concentration of protein (mg protein/mL solution) in the original sample. Carry out your result to 4 significant figures.
