xxx xxxx of xxxx contained xx lead(II)acetate is:

m(Pb) = xxxxx * xxxxxxxxxxxxxx

where w(Pb) is the mass fraction of lead in xxxxxxxxxxxxxxxx xx xxx calculate xx xx xxxxxxxx

xxxxx x M(Pb) / xxxxxxxxxxxxxxx

or the xxxxxx xx the xxxxx xxxxxx of lead and lead(II)acetate. We xxxx xxxxx values xxxx xxx xxx we xxxxx

M(Pb) x xxxxx g/mol

xxxxxxxxxxxxxx = xxxxx + xxxxxxxxx + 2*M(O) + xxxxxxx x xxxxx + xxxxxx x 4*M(O) x xxxxxx x [207.2 x 4*12.01 x xxxxxxx + 6*1.01] xxxxx x xxxxxx xxxxx

xxxx xx can xxxxxxxxx xxxxxx

xxxxx x xxxxx / M(Pb(CH3COO)2)

w(Pb) x 207.2 g/mol / xxxxxx xxxxx

w(Pb) x 207.2 / 325.29

w(Pb) x xxxxxxx

xxxx xxx xxxx of lead is:

xxxxx x xxxxx x m(Pb(CH3COO)2)

xxxxx x 0.63697 x 0.9020 g

m(Pb) = xxxxxx x
