First, write down the reaction equation.
Mg + Cl2 = MgCl2.

When magnesium reacts with chlorine, magnesium chloride is formed.

Next, determine the molar mass of magnesium.
M (Mg) = 24 g / mol.

Therefore, the molar mass of magnesium is 24 g / mol.

Next, determine the molar mass of magnesium chloride.

M (MgCl2) = 24 + 2 * 35.5 = 24 + 71 = 95 g / mol.

Therefore, the molar mass of magnesium chloride is 95 g / mol.

Next, use the reaction equation to determine the mass of magnesium chloride.
36 g magnesium – x g magnesium chloride.

24 g / mol magnesium – 95 g / mol magnesium chloride.

Determine the unknown value of x.

X = 36 * 95: 24 = 142.5 g.

Therefore, the mass of the obtained magnesium chloride is 142.5 grams.

Answer: the mass of magnesium chloride is 142.5 g.
