4. A sample of processed meat scrap weighing 4.000 g is digested with concentrated H:SO, and Hg(catalyst) until the Npresent has been converted to NH&HSO.. This is treated with excess NaOH, and the liberated NH3 is caught in a 100-ml. of H;SO. ( Iml = 0.01860 g Na,O). The excess acid requires 57.60 ml of NaOH ( Iml = 0.12660 g potassium acid phthalate, KHCaH.O). Calculate the percentage protein in the meat scrap
