Question

calculate the no of moles of zinc ions and chloride ions which will be obtain from 272g of zinc chloride​

Answer 1

Answer: 0.5 moles of zinc and 1.5 moles of chloride ions.

Explanation:

Molecular Weight of $ZnCl_{2}$ =136

So the number of moles of ZnCl2= 272/136 = 2moles

One mole of ZnCl2 has one mole of zinc and 2 moles of chloride ions

therefore from 272g of ZnCl2  1.5 moles of Chloride ions and 0.5 moles of Zinc ions are released.
