Moles of lead (II) acetate
"n(Pb(CH_3COO)2) =\\frac{m}{M} = \\frac{21.9 g}{325.29 \\frac{g}{mol}}=0.0673 mol"1) Molarity of the solution
2) When this salt gets into water it dissociates
As 1 mole of "Pb(CH_3COO)_2" gives 1 mole of "Pb^{2+}" , then moles of "Pb^{2+}"
"c(Pb^{2+})=\\frac{n}{V}=\\frac{0.0673 mol}{0.5 L} = 0.135 M"
3) as 1 mole of "Pb(CH_3COO)_2" gives 2 moles of "CH_3COO^-" ,then moles of "CH_3COO^-"
