test tube:                                     1.                 2.                      3.                      4.                   Sat. soln of PbI2

mL 0.012 M Pb(NO3)2                 5                  5                       5                       5

ml 0.03 M KI.                             2 mL.            3 mL.                4 mL.                5mL

mL 0.20 M KNO3.                      3 mL.            2 mL.                1 mL.                0 mL.

Total volume in mL.                    10.                10.                    10.                     10.  

Absorbance of soln.                   0.77.             1.29.                (Broken).            0.080.            0.134

[I] in mol/L at equilibrium.             ?                  ?                          ?                         ?                           ?

Calculations:

Initial # mol Pb2+.               ?* 10 ^(-5).         ?* 10 ^(-5).       ?* 10 ^(-5).        ?* 10 ^(-5)

Initial # mol I                        ?* 10 ^(-5)          ?* 10 ^(-5).       ?* 10 ^(-5).       ?* 10 ^(-5)

# mol at equilibrium.             ?* 10 ^(-5)         ?* 10 ^(-5).        ?* 10 ^(-5).      ?* 10 ^(-5)

# mol I precipitated.              ?* 10 ^(-5).        ?* 10 ^(-5).       ?* 10 ^(-5).       ?* 10 ^(-5)

# mol Pb2+ precipitated.       ?* 10 ^(-5).        ?* 10 ^(-5).       ?* 10 ^(-5).         ?* 10 ^(-5)

# mol Pb2+ at equilibrium  ?* 10 ^(-5).            ?* 10 ^(-5).        ?* 10 ^(-5).        ?* 10 ^(-5)

[Pb2+] at equilibrium.              ?                             ?                         ?                      ?                     ?

 

*I need help finding the molarity of I and Pb2+ at equilibrium. As well as the calculation portion*

Please provide us the complete data.

This is the complete data.  I need to find molarity from the absorption.
