Stoichiometry
The calculation of quantities in chemical reactions
Most important for stoichiometry
Having a balanced equation
Bridge between compounds A and B?
Moles! (use equation coefficients)
Where to start on stoichiometry road map?
Always at side A
Grams A to Moles A
Use molar mass
Moles A to Molecules A
Use Avogadro's number
Moles A to Moles B
Use equation coefficients
Moles B to Grams B
Use molar mass
Moles B to Molecules B
Use Avogadro's number
% yield equation
experimental yield/theoretical yield x 100
Theoretical yield is determined by
The stoichiometry calculation
Experimental yield is determined by
What is done in lab
will be given on exam
Use _________________ when setting up theoretical yield calculation
Dimensional analysis
When given 2 possible starting quantities and compounds...
Do dimensional analysis to find theoretical yield for each compound. The one with the LOWER yield is the one that should be used in the % yield equation
Why is the lower yield used when 2 possible quantities/compounds are given?
This is the limiting agent for the reaction. No more can be produced than this allows.
