Determine the molar concentration if a 250 ml solution contains 60 g aluminum chloride.

Let’s calculate the chemical amount of a substance in 60 grams of aluminum chloride.

M AlCl3 = 27 + 35.5 x 3 = 133.5 grams / mol;

N AlCl3 = 60 / 133.5 = 0.449 mol;

If 250 ml contains 0.449 mol of the substance, therefore, 1 liter will contain 0.449 x 4 = 1.796 mol of salt.

The molar concentration of salt is 1.796 mol / liter;
