<h3>Answer;</h3>

= 13.629 g of ZnCl2

<h3><u>Explanation;</u></h3>

The equation for the reaction.

Zn(s)+2HCL(aq)=>ZnCl2(aq)+H2(g)

Number of moles of Zinc;

Moles = mass/RAM

          = 6.5 g/65g/mol

          = 0.1 moles

The mole ration of Zn : ZnCl2 is 1 : 1

Therefore, number of moles of ZnCl2 is 0.1 moles

Mass = moles × Molar mass

         = 0.1 ×136.286 g/mol

        <u> = 13.629 g</u>
