How many liters of hydrogen will be released when hydrochloric acid interacts with 2.7 aluminum.
| July 28, 2021 | education
The reaction of aluminum with hydrochloric acid is described by the following formula:
2Al + 6HCl = 2AlCl3 + 3H2;
From 2 moles of aluminum, 3 moles of hydrogen are formed.
The molar mass of aluminum is 27 grams / mol.
Accordingly, 2.7 grams contain 2.7 / 27 = 0.1 mol of the substance.
With that amount of aluminum, you can get 0.1 x 3/2 = 0.15 mol of hydrogen.
Under normal conditions, 1 mole of ideal gas takes up a volume of 22.4 liters.
0.15 mol of hydrogen occupies a volume of 0.15 x 22.4 = 3.36 liters.
