Given data:

Calculations:

The molar mass of aluminium (Al) is 26.98 g/mol.

The number of moles of aluminium is calculated as shown below.

The given reaction is shown below.

In the above reaction, 2.0 mol of aluminium (Al) produces 3.0 mol of hydrogen gas (H2). Therefore, the number of moles of hydrogen gas produced by 0.234 mol of aluminium (Al) is calculated as shown below.

At STP, the pressure (P) is 1.0 atm and temperature (T) is 273.15 K. The volume of the hydrogen gas is calculated by the formula shown below.

Substitute the given data in above equation (I).
