Answer
0.406M
Explanation
Number of moles = mass /molar mass
number of moles of Pb(CH3COO)2 = 13.2g /325.3g/mol = 0.04058mol
Number of moles of CH3COO- = 2×0.04058mol = 0.08116mol
molarity = number of moles of solute per liter of solution
Final molarity of acetate anion in the solution = (0.08116mol/200ml)×1000ml = 0.406M
