Question- The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 6.63-g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb3 (aq). The Sb3 (aq) is completely oxidized by 30.1 mL of a 0.125 M aqueous solution of KBrO3(aq).

Calculate the amount of antimony in the sample and its percentage in the ore.
