Answer: 10.86 moles
Explanation: For the given chemical reaction. 2 moles of lead combines with 2 moles of lead oxide and 2 moles of sulphuric acid to produce 2 moles of lead sulphate and 2 moles of water.
[tex]Pb+PbO_2+2H_2SO_4\rightarrow 2PbSO_4+2H_2O [/tex]
1 mole of lead oxide [tex](PbO_2)[/tex] produces 2 moles of water[tex](H_2O)[/tex]
Thus 5.43 moles of lead oxide [tex](PbO_2)[/tex] produces =[tex]\frac{2}{1}\times 5.43=10.86[/tex] moles of water[tex](H_2O)[/tex]
