How to do Stoichiometry Woo~
By Kenny Vu
What is this "stoichiometry" you want to learn about?
Where would you start?
Balanced Equation: Na2SO4(aq)+Sr(NO3)2(aq)->SrSO4(s)+2NaNO3(aq)
Molar mass for each reactant and product
Now for the great math part!
mole to mole conversions
mass to mass conversions
Limiting and excess reactant
Theoretical yield, actual yield, and percent yield
Actual yield is how much product is actually made from the experiment, for us it's given as 11.3g of strontium sulfate.
Percent yield is the percentage of how much product is made in comparison to how much should've been made and you find that by dividing actual yield by theoretical yield and then multiplying by 100. The percent yield for the example reaction should then be 105%.
