Answer #1

Correct answer is : 1.07*10^3 g

Explanation

mass H2SO4 = 1.50 kg = 1500 g

moles H2SO4 = (mass H2SO4) / (molar mass H2SO4)

moles H2SO4 = (1500 g) / (98.08 g/mol)

moles H2SO4 = 15.3 mol

theoretical moles H2SO4 = (actual moles H2SO4 produced) / (fraction yield)

theoretical moles H2SO4 = (15.3 mol) / (0.771)

theoretical moles H2SO4 = 19.8 mol

actual moles SO3 consumed = theoretical moles H2SO4 produced

actual moles SO3 consumed = 19.8 mol

theoretical moles SO3 produced = (actual moles SO3 produced) / (fraction yield)

theoretical moles SO3 produced = (19.8 mol) / (0.771)

theoretical moles SO3 produced = 25.7 mol

actual moles SO2 consumed = theoretical moles SO3 produced

actual moles SO2 consumed = 25.7 mol

Theoretical moles SO2 produced = (actual moles SO2 consumed) / fraction yield)

Theoretical moles SO2 produced = (25.7 mol) / (0.771)

Theoretical moles SO2 produced = 33.4 mol

moles S8 consumed = (Theoretical moles SO2 produced) / 8

moles S8 consumed = (33.4 mol) / 8

moles S8 consumed = 4.17 mol

mass S8 = (moles S8) * (molar mass S8)

mass S8 = (4.17 mol) / (256.52 g/mol)

mass S8 = 1070 g

mass S8 = 1.7 x 103 g
