You have the definition of mole wrong, it is actually 6.022*10^23 units like atoms or molecules. So you need to find out how much 1 mole (or mol) of Zn, I and ZnI weighs in grams first, then you convert your weights to moles by dividing measured weight with mole weight. Then I think you'll pick the smalles value of the three and divide all the mole values with that, so you can see the proportions more clearly. One (the smallest) will be 1 and the rest will be bigger than 1.

I hope this helps.
