Question 5: Stolchlometry (8 polnts)
Use the balanced equation below to answer the following questions.
2Al(NO3)3 + 3Na2CO3 → Al2(CO3)3(s) + 6NaNO3
a. What is the ratio of moles of AI(NO3)3 to moles Na2CO3? (1 point)
b. If 852.04 g Al(NO3)3 reacted with the 741.93 g Na2CO3, which would be the limiting reagent? Show
your work. (3 points)
c. Use the limiting reagent to determine how many grams of Al2(CO3)3 should precipitate out in the reaction. (2 points) d. If only 341.64 g of Al2(CO3)3 precipitate were actually collected from the reaction, what would the percent yield be? (2 points)
