Given the following balanced equation determine the amount of MgCl2 that can be produced from 65.0 grams of Mg. Mg + HCl  MgCl2 + H2

Answer 1

The equation as given IS NOT balanced. So, we will balance it first, and then proceed.

Mg + 2HCl ==> MgCl₂ + H₂

We can use the stoichiometry of the balanced equation along with dimensional analysis to find the mass of MgCl2 that can be produced from 65.0 g of Mg.

65.0 g Mg x 1 mol Mg/24.3g x 1 mol MgCl₂/mol Mg x 95.2 g MgCl₂/mol = 255 g MgCl₂
