A mixture of gases liberated upon decomposition of 33.1 gm of lead (II) nitrate is dissolved in 10 ml of water. What is the mass (in g) of 0.1 M KOH solution with density of 1.05 g/ml required to neutralize this acid. The reactions are:
`2Pb(NO_(3))_(2)rarr2PbO+4NO_(2)+O_(2)`
`KOH+HNO_(3)rarrKNO_(3)+H_(2)O`
[Atomic mass of Pb=207]
