Pb + pbo2 + 2h2so4 2pbso4 + 2h2o how many moles of water are produced if 5.43 mol pbo2 are consumed?

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.

1 mole of lead oxide produces 2 moles of water

Thus 5.43 moles of lead oxide produces = moles of water
