Your problem isn't chemistry. You just need a little help with algebra. 5.00-4.74 = 0.26 = log 15/x 15/x = antilog 0.26 = 1.82 So 1.82 = 15/x. Solve for x and convert to g/500 mL.

The number is correct but look at the algebra. I don't think you have 8 mols S8; you have 1 mol S8. Check this out. mols H2SO4 = 138/98. OK. Convert to mols S8. That will be 138/98 x (1 mol S8/8 mol H2SO4). Now convert that to g S8 138/98 x (1/8) x (molar mass S8) = 138/98 x (...
