Zn + S → ZnS How do you do this? | Yahoo Answers

2009-10-22 · multiply this by the molar mass of ZnS. (0.2027448 x 97.44) =19.755g ZnS. Since there is only 12.0 + 6.5 = 18.5 g of total substance, we cannot make 19.755 g of ZnS, because that would mean we end up with more than we had before, which isnt possible. Therefore, the correct answer would be what we found for Zn, which would be 17.884g ZnS. ...
