The mass of MgCl₂ produced is 5.685 grams.
<h3>What is mass?</h3>
Mass is the quantity of matter of a physical body.
The reaction is
Mg + 2HCl → MgCl₂ + H₂
2 mole of HCl
(2 × 36.458) = 72.8 g
1 moles of MgCl₂
(1 × 95.21 g) = 95.21 g
1 g Mg will produce = 
4.67 mol Mg will produce
Thus, the mass of MgCl₂ produced is 5.685 grams.
