. A student prepares a solution by dissolving 1.000 mol ofNa2SO4 in water. She accidentally leaves the containeruncovered and comes back the next week to find only awhite, solid residue. The mass of the residue is 322.2 g.Determine the chemical formula of this residue.
A sample of processed meat scrap weighing 4.000 g is digested with concentrated H2SO4 and Hg(catalyst) until the N present has been converted to NH4HSO.. This is treated with excess NAOH , and the liberated NH3 is caught in a 100-ml of H2SO4 ( Iml = 0.01860 g Na,O). The excess acid requires 57.60 ml of NaOH ( Iml = 0.12660 g potassium acid phthalate, KHCaH.O4). Calculate the percentage protein in the meat scrap
