mols HCl you have = M x L = ?
mols Mg needed = 1/2 mols HCl because you know 1 mol Mg reacts with 2 mols HCl.
grams Mg = mols Mg x atomic mass Mg.
How many grams of magnesium metal will react completely with 5.2 liters of 4.0 M HCl? Show all of the work needed to solve this problem.
Mg (s) + 2HCl (aq) MgCl2 (aq) + H2 (g)
