Show all your calculation work to solve the following mass-mass stochiometry problem;

How many grams of zinc (II) chloride (ZnCl2) are produced if 6.5 grams of zinc (Zn) are used in a chemical reaction according to the following equation.

Zn(s) + 2HCl(aq) --> ZnCl (aq) + H2 (g)

Note! Before you solve you must calculate the molar of all the compounds in the equation. Calculate the molar mass exactly as shown in the example attached.

Next. You must provide the given chemical and desired.

Then solve EXACTLY like the example attached. Be sure to provide the significant figure rule to your final answer which is also attached.
