Zinc reacts with iodine in a synthesis reaction. Determine the theoretical yield if a 125.0g sample of zinc was used.

    Stoicheometry my dear Watson.  First, you need to figure out what compound you are making as a product.  Write the chemical equation out and balance it.  Then, you can turn moles of zinc (I’ll help you out here and tell you that zinc has a molecular weight of 65.38 grams per mole).  Now convert the number of moles you use of zinc as a reactant, into the number of moles of product formed.  Now, you have to see what ratio this yield is based on the zinc used as a starting material. 

    Consult your chemistry text for more help, I am sure the answers are in there…but not here.
