Solution: One rather exotic compound synthesized by the Susan Latturner group is Ba 2In5P5. (See Chemistry of Materials, 2008, 20, 5675-5681.) One could imagine attempting to prepare Ba2In5P5 by the following reaction: 2BaBr2 + 6 InP → Ba2In5P5 + InBr + PBr3 (Note: All of these compounds are real, but the reaction is hypothetical.) The following molar masses might come in handy: BaBr2 297.14; InP 145.79; Ba2In5P5 1003.61; all units are g/mol.   a) Suppose the reaction is carried out with 110 g of BaBr2 and 210 g of InP. What is the limiting reagent?        b) How much (mass in grams) Ba2In5P5 would you make if the reaction went to completion?    c) After isolating and purifying the product, you only obtained 56 g of Ba2In5P5. What was your percent yield?

Problem

One rather exotic compound synthesized by the Susan Latturner group is Ba 2In5P5. (See Chemistry of Materials2008, 20, 5675-5681.)

One could imagine attempting to prepare Ba2In5P5 by the following reaction:

2BaBr+ 6 InP → Ba2In5P5 + InBr + PBr3

(Note: All of these compounds are real, but the reaction is hypothetical.)

The following molar masses might come in handy: BaBr297.14; InP 145.79; Ba2In5P5 1003.61; all units are g/mol.

 

a) Suppose the reaction is carried out with 110 g of BaBr2 and 210 g of InP. What is the limiting reagent? 

 

 

 

b) How much (mass in grams) Ba2In5P5 would you make if the reaction went to completion? 

 

c) After isolating and purifying the product, you only obtained 56 g of Ba2In5P5. What was your percent yield?
