Weightlifting - Stoichiometry
No sport represents a bigger strain on the body than the weightlifting that is involved for stoichiometric conversions. From the rather simple reps of converting grams to moles, to the 400 pound dead lift of limiting reactants and empirical formulas.
In order to earn the gold in this event you will need to be able to do all types of stoichiometry conversions, limiting reactant problems, and molarity calculations. |
Calculating Molarity
Recall that we calculate the molarity of a solution using the equation:
In addition to calculating the molarity of a solution, we often work with stock solutions. These are more concentrated solutions that can be diluted to larger volumes in order to make a less dilute solution. We calculate the concentration (or volume) of this new solution using the equation:
M1V1=M2V2
Stoichiometry, Empirical Formulas, and Limiting Reactants
Oh stoichiometry...we cringe when we hear this word, but this is one of the most essential things that we learn in chemistry. It truly is a huge weight that many of us need to lift, but we need to be do all of the components of it if we are going to be gold medalists in this event! Recall that our Road Map gives us a clear way to convert between grams, moles, particles, and volume of a certain substance. Review the road map below:

The Main Event!
Are you ready for the 400 pound dead lifts? Do you think you can stare down the scary Russian man that could likely crush your head with his index finger? If you answered yes, then you are ready to complete the FRQ for stoichiometry! NOTE - If you need to retake this FRQ, then see Mr. Astor for
