The solution contains aluminum ions in an amount of 0.2 mol. Calculate the mass of aluminum ions that are contained in this solution.

n (Al) = 0.2 mol.

Let’s determine the mass of aluminum. We use the following formula.

n (Al) = m / M.

Where n is the amount of substance.

m is the mass of the substance.

M is the molar mass of the substance.

Let’s determine the molar mass of oxygen. We write down the solution.

M (Al) = 27 g / mol.

m = n * M = 0.2 * 27 = 5.4 g Al.

This means that the mass of aluminum is 5.4 grams.

Answer: The mass of 0.2 mol of aluminum is 5.4 grams.
