Solution reaches equilibrium

1. A 120.0 −mL sample of a solution that is 3.0×10−3M in AgNO3 is mixed with a 230.0 −mL sample of a solution that is 0.14 M in NaCN.

After the solution reaches equilibrium, what concentration of Ag+(aq) remains?
Express your answer using two significant figures.
B. A 0.5210 −g sample of an unknown monoprotic acid was titrated with 9.96×10−2 M NaOH. The equivalence point of the titration occurs at 23.88 mL.

Determine the molar mass of the unknown acid.

2.Use the Ksp values to calculate the molar solubility of each of the following compounds in pure water.
