sulfuric acid can be prepared by a multistep process summarized as: 2 SO2 + O2 + 2 H2O--> 2 H2SO4 What mass of sulfuric acid could be produced daily by a process using 38 kg per day of sulfuric dioxide with a 70% conversion efficiency ("yield"), assuming that sulfuric dioxide is the limiting reagent
Answer: 41 kg/day

I don't know how to get this answer. someone help!

  1. mols SO2 = 38000/molar mass SO2 = ?
    mols H2SO4 produced = same as mols SO2 becaue 2 mol SO2 = 2 mol H2SO4.
    Then grams H2SO4 = mols H2SO4 x molar mass H2SO4 = ? g, then convert to kg. That's if the process were 100% efficiency. It isn't so that answer x 0.70 = the amount produced at 70% efficiency.
