Silver nitrate is an inorganic compound with chemical formula AgNO
3. This compound is a versatile precursor to many other silver compounds, such as those used in photograthy.
Lead is a soft, malleable and heavy post-transistion metal with the symbol Pb.
Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2
Mole to Mole Conversions
When i did this conversion through the table my "Mole A" (given from question) was 2.11 moles of Pb. My "Mole B" (Ag(NO3)) had the Coefficient of 2. And my second "Mole A" had a Coefficient of 1. Multiplying by the top then Dividing by the bottom i got
4.22 moles of (Ag(NO3)).

Mass to Mass Conversions
In my Reaction
12.1g Pb- Grams A
207.2g Pb- Molar mass of Gram A
2- Coefficient of mole B
1- Coefficient of mole A
169.872g Ag(NO3)- Grams B
I multiplied across the top then divided by the bottom and came out with 19.8g of (Ag(NO3))
In my case Ag(NO3) was my Limiting Reactant because there was the least amount of it in the reaction.
In my reaction Pb is my excess reactant because i have it left over.
The Reaction that comes out the least is the theoretical, because there is less and it limits the reaction to that amount.
In my equation the theoretical yield is (7.18 Ag) compared to (12.806 Pb), Ag is the theoretical yield because it is the smallest.
(Actual) / (Theoretical) x (100)= (Percent Yield)
7.81g of Ag- Theoretical
9.02g of Ag- Actual
9.02 / 7.81 x 100= (115.4%)
115.4% is my Percent Yield
