help solve to check if I'm right

Post by ggpenguin »

the compound sodium thiosulfate pentahydrate, Na2S2O3*5H2O, is important commercially to the photography business as "hypo" because it has the ability to dissolve unreacted sliver salts from photographic film during development. Sodium thiosulfate pentahydrate can be produced by boiling elemental sulfur in aqueous solution of sodium sulfite.
S8 + Na2SO3 + H2O = Na2S2O3 * 5H2O (unbalanced)

What is the theoretical yield of sodium thiosulfate pentahydrate when 3.25g of sulfur is boiled with 13.1g of sodium sulfite? Sodium thiosulfate pentahydrate is very soluble in water. What is the percent yield of the synthesis if a student doing this experiment is able to isolate (collect) only 5.26g of the product.
