Question

Zinc reacts with hydrochloric acid according to the reaction equation shown.

Zn(s)+2HCl(aq)⟶ZnCl2(aq)+H2(g)Zn(s)+2HCl(aq)⟶ZnCl2(aq)+H2(g)

How many milliliters of 4.504.50 M HCl(aq) are required to react with 7.557.55 g of an ore containing 49.049.0% Zn(s) by mass?

volume:

mL

Step 1

The gram of Zn can be calculated as

Step 2

The reaction of zinc with hydrochloric acid is shown as,

Step 3

It is required to calculate the volume in mL of 4.50 M HCl which will react with 3.7031 g of Zinc.
