**Precipitation Reaction Problem****Question:**A 185.0 mL sample of 1.200 M Pb(NO₃)₂ is mixed with 123.50 mL of 1.500 M NaCl, and the PbCl₂ precipitate is filtered from the solution. Then 200.0 mL of 3.000 M NaBr is added to the remaining solution, and the PbBr₂ precipitate is also collected and dried. What is the mass (in grams) of the PbBr₂ precipitate, assuming the yield in each precipitation step is 100%?**Analysis:**1. **Reaction 1: Formation of PbCl₂** - Solutions mixed: 185.0 mL of 1.200 M Pb(NO₃)₂ and 123.50 mL of 1.500 M NaCl. - Precipitate formed: PbCl₂. 2. **Reaction 2: Formation of PbBr₂** - Remaining solution: After filtration of PbCl₂. - Added solution: 200.0 mL of 3.000 M NaBr. - Precipitate formed: PbBr₂. **Objective:**Calculate the mass of the PbBr₂ precipitate.**Key Assumptions:**- 100% yield for each precipitation step. **Calculation Steps:**- Determine moles of each reactant.- Identify the limiting reactant for each reaction.- Calculate moles of PbBr₂ formed.- Convert moles of PbBr₂ to grams using its molar mass.
