| Let’s implement the solution:

Let’s compose the reaction equation: 2Na + 2HCl = 2NaCl + H2 – ОВР, hydrogen evolved

Determine the number of moles of sodium by the formula: Y (Na) = m (Na) / M (Na);

Y (Na) = 4.6 / 22.9 = 0.2 mol;

Let’s write the proportion according to the reaction equation:

0.2 mol (Na) – X mol (H2);

X mol (H2) = 0.2 * 1/2 = 0.1 mol;

Let’s calculate the volume of hydrogen according to Avogadro’s law:

V (H2) = 0.1 * 22.4 = 2.24 liters.

Answer: when sodium interacts with hydrogen chloride, 2.24 liters of hydrogen was released.
