What mass of AlCl3 is formed as a result of the chemical reaction of aluminum. Chemical amount 0.3 mol

What mass of AlCl3 is formed as a result of the chemical reaction of aluminum. Chemical amount 0.3 mol with hydrochloric acid?

We draw up the equation of the ongoing reaction and place the coefficients in it:
2Al + 3Cl2 = 2AlCl3.
1) Consider the reaction equation. According to the reaction, we see that for two moles of aluminum there are two moles of aluminum chloride. This means that the amount of chloride substance is equal to the amount of pure aluminum substance and is equal to 0.3 mol.
2) The molar mass of aluminum chloride is: 27 + 35.5 * 3 = 133.5.
3) Calculate the mass of aluminum chloride. To do this, we multiply the amount of chloride substance by its molar mass: 133.5 * 0.3 = 40.05 g – the answer.
