the chemical reaction to produce sulfuric acid fro lead (ii) sulfate is:
PbSO4 + SO2 + 2H2O --> Pb + 2H2SO4
first convert the mass of PbSO4 to moles
moles PbSO4 = 68.1 g ( 1 mol / 303.26 g )
moles PbSO4 = 0.2246 mol PbSO4
mass H2SO4 = 0.2246 mol PbSO4 ( 2 mol H2SO4 / 1 mol PbSO4) ( 98 g / mol)
mas H2SO4 = 44 g H2SO4
