Frankly, I understood only a sentence or two of your post. Poor punctuation and run on sentences was partly to blame (as well as spelling where as were); however, some of the problem just escapes me. I think you have made it far to complicated. Here is how you do the problem.
mols Au in 29.0 g Au =
moles = grams/molar mass = 29.0/196.97 = 0.147 moles Au.
Now convert moles Au to mols KCN using the coefficients in the balanced equation.
0.147 moles Au x (8 moles KCN/4 moles Au) = 0.147 x 2 = 0.294 moles KCN.
I sense you are confused that the moles KCN should be 8 moles while you obtained 0.294 moles. The 0.294 mole KCN is the correct answer when 29.0 g Au is separated; the 8 moles KCN is the correct answer when 4*197.9 g Au (4 moles Au) is separated.
