How many grams of iron will be required to release as much hydrogen with hydrochloric acid as it is released

How many grams of iron will be required to release as much hydrogen with hydrochloric acid as it is released by the interaction of 0.5 mol of sodium with water.

reaction of sodium with water:
2Na + 2 Н2O = 2NaOH + H2
When 1 mol of Na interacts with water, 0.5 mol of hydrogen is released (according to the equation).
Reaction of aluminum with hydrochloric acid
2Al + 6HCL = 2AlCl3 + 3H2
According to the reaction equation, 3 moles of hydrogen are released when 2 moles of aluminum react with an acid.
Hence the amount of aluminum: (0.5 / 3) * 2 = 0.33 mol
The mass of aluminum will be: 27 * 0.33 = 9 g
