How many grams of zinc chloride could be formed from the reaction of 3.57g of zinc with excess hcl?

6.8 grams of zinc chloride

Explanation:

is a limiting reagent as it limits the formation of products and is an excess reagent.

According to stoichiometry:

As 1 mole of gives= 1 mole of

0.05 moles of will give= of

Mass of

Thus 6.8 grams of zinc chloride could be formed from the reaction of 3.57g of zinc with excess HCl.
