Calculate the number of moles of 2 4-pentanedione you will use

1)Calculate the number of moles of 2 4-pentanedione you will use (density of 2 4-pentanedione= 0.976g mL^-1 GMM: 100.11 g mol^-1).2)Calculate the theoretical yield in moles of Fe(C5H7O2)3The success of this synthesis depends on the fact that KNO3 is much less soluble in water than KI NaNO3 or NaI. When she dissolved 0.50 mol KI and 0.75 mol NaNO3 in 100 mL of water and cooled the solution to 0 degrees C 37 g of pure KNO3 crystallized from solution.1) What is the theoretical yield in grams of KNO3 for this synthesis?2) What is her percent yield for this synthesis?
