Atoms,_Molecules_and_Ions : MassInAlloy (10 Variations)
Gold is alloyed with other metals to make it less malleable. 10 karat gold is an alloy that is 41.7% gold. How much pure gold is in a 20. gram 10 karat gold ring?
Stoichiometry
Stoichiometry : GramMoleProblem (9 Variations)
Which sample contains the largest number of nitrogen atoms?
Stoichiometry
Stoichiometry : LimitingReagent (8 Variations)
The synthesis of urea by Frederich W??hler in 1825 began the decline of the idea that "organic" chemicals could only be made by living organisms as part of their biological processes.

AgOCN(aq) + NH4Cl(aq)AgCl(s) + NH2CONH2(aq)

If you perform this reaction and collect the following table of data, in which trial(s) is AgOCN clearly the limiting reactant?

Trial AgOCN used NH4Cl AgCl produced
1 20.4 mL 5.3 mL 2.4 g
2 20.3 mL 10.4 mL 4.3 g
3 20.6 mL 15.4 mL 6.2 g
4 20.5 mL 20.6 mL 8.2 g
5 20.4 mL 25.2 mL 10.2 g
6 20.3 mL 30.4 mL 10.3 g

The mL of AgOCN and NH4Cl are the initial amounts used, the mass of AgCl is how much was recovered from the reaction. (Hint: You do not need to do any calculations to answer this question.)

Using Limiting-Excess Stoichiometry to Introduce Equilibrium Calculations: A Discrepant Event Laboratory Activity Involving Precipitation Reactions  Stephen DeMeo
Students are introduced to the concept of equilibrium as they investigate two precipitation reactions, predict which reactant is present in excess, and find that there are two excess reactants.

Preparation and Analysis of Multiple Hydrates of Simple Salts  Richard W. Schaeffer, Benny Chan, Shireen R. Marshall, Brian Blasiole, Neetha Khan, Kendra L. Yoder, Melissa E. Trainer, and Claude H. Yoder
A laboratory project in which students prepare a series of hydrates of simple salts and then determine the extent of hydration of the product(s); provides a good introduction to the concepts of solubility, saturation, recrystallization, relative compound stability, and simple gravimetric analysis.
Schaeffer, Richard W.; Chan, Benny; Marshall, Shireen R.; Blasiole, Brian; Khan, Neetha; Yoder, Kendra L.; Trainer, Melissa E.; Yoder, Claude H. J. Chem. Educ. 2000, 77, 509.
