Question
In an experiment, 6.700g of hydrogen sulfide is fully decomposed into its elements.If 0.396g of hydrogen is obtained in this experiment, how many grams of sulfur must be obtained?

H2S ==> H2 + S
mols H2S = grams/molar mass
mols H2 = mols H2S (from the coefficients).
g H2 = mols x molar mass. This is the theoretical yield.
% yield = (0.396/theor yield)*100 = ?
Then mols H2S x molar mass S x (theor yield/100) = g S.
