Asked by Gina
A student reacted 0.500g of Pb(NO3)2 with 0.750g of KI according to the reaction,
Pb(NO3)2(aq) + 2KI(aq)=PbI2(s) + 2KNO3(aq)
A) How many moles of Pb(NO3)2 were used?
B) How many moles of KI were used?
C) How many moles of PbI2 would form,
based on the moles of Pb(NO3)2 used?
D) How many moles of PBI2 would form,
based on the moles of KI used?
E) Which is the limiting reactant?
F) What is the theoretical yield of
PbI2 in grams?
G) If the student obtained 0.583 grams
of PbI2 product after collecting it
by filtration and drying it, what
was the percent yield of PbI2
obtained?
