###### FREE Expert Solution

We’re being asked to determine the solubility (in M) of PbBr2 after 5.00 L of the 1.00x10-3 M of the CaBr2 solution has been added to 500 mL of the 2.0 M Pb(NO3)2.

We’re going to calculate the solubility of PbBr2 using the following steps:

Step 1: Calculate the moles of Pb2+ from Pb(NO3)2.
Step 2: Calculate the moles of Br- from CaBr2.
Step 3: Determine the excess and calculate the concentration of the remaining excess reactant.
Step 4: Create an ICE chart for the dissociation of PbBr2.
Step 5: Calculate the solubility of PbBr2.
