It is synthesized from K2PtCl2 (aq) and aqueous ammonia in a reaction that procedure KCl and cisplatin (aq). 5.00 ml of 0.0120 M K2PtCl4 (aq) is mixed with 3.00ml of 0.0562 M aqueous ammonia, and the reaction proceeds to completion, producing 0.00916 g cisplatin. The antitumor agent cisplatin (Pt(NH3)2Cl2) has been used to treat a variety of cancers for nearly 30 years. Determine the percent yield of cisplatin?
