Question

Mixing the following solutions resulted in the isolation of 1.25 g of Ag2CrO4.

51.40 mL of 0.187 M AgNO3
36.80 mL of 0.119 M K2CrO4

I can't figure out the last part. Please help!!

Complete the following reaction table in millimoles CrO4 Ag2CrO4 Ksp = 1.1e-12 mmol mmol mmol 2Ag initial 9.61 delta -8.76 final 0.85 What is the theoretical yield of Ag2CrO4? 4.38 4.38 4.38 4.38 1.45 What is the percent yield of Ag2Cr04? 86.21 Assume additive volumes to determine the equilibrium concentration of the excess reactant. 0096 Determine the equilibrium concentration of the limiting reactant. 6.50e-05 X M

Explanation / Answer

Limiting reagent is something which actually limits the reaction occurance further. So, the limiting reagent is K2C2O7 as less amount of moles are present as compared to AgNO3.

At equilibrium, you can see that 0 moles are present.

So, equilibrium conc of limiting reagent = 0moles/total volume = 0M
