How many grams of zinc metal will react completely with 5.4 liters of 2.8 m hcl? show all of the work needed to solve this problem. zn (s) + 2 hcl (aq) yields zncl2 (aq) + h2 (g)

Answer : The amount of zinc metal react will be, 494.27 grams.

Solution : Given,

Volume of HCl solution = 5.4 L

Molarity of HCl solution = 2.8 M

Molar mass of zinc (Zn) = 65.38 g/mole

First we have to calculate the moles of HCl.

Now we have to calculate the moles of Zn.

The given balanced chemical reaction is,

From the balanced reaction, we conclude that

As, 2 moles of react to with 1 mole of Zn

So, 15.12 moles of react to with moles of Zn

Now we have to calculate the mass of Zn.

Therefore, the amount of zinc metal react will be, 494.27 grams.
