Question

The compound cisplatin, Pt(NH3)2Cl2, has been studied extensively as an antitumor agent. It can be synthesized as follows:

K2PtCl4 (aq)

+

2NH3 (aq)

Pt(NH3)2Cl2 (s)

+

2KCl (aq)

415.09 g/mol

 

17.0304 g/mol

 

300.05 g/mol

 

74.551 g/mol



You are a research chemist for a pharmaceutical firm and you have 0.4256 g of K2PtCl4 and 0.2135 g of NH3. Given these quantities, what is the theoretical yield of cisplatin? Report your answer to 4 significant figures.

 

If your actual yield of cisplatin is 0.2475 g and using the theoretical yield from the previous problem where you had 0.4256 of K 2PtCl 4 and 0.2135 g of NH 3, what is the percent yield?  Report your answer to 4 significant figures.
