What amount of hydrogen is formed by the interaction of 2.3 g of sodium with sulfuric acid?

Let’s write the reaction equation:

2Na + H2SO4 = Na2SO4 + H2 ↑

Let’s find the amount of sodium substance:

v (Na) = m (Na) / M (Na) = 2.3 / 23 = 0.1 (mol).

According to the reaction equation, 1 mol of H2 is formed per 2 mol of Na, therefore:

v (H2) = v (Na) / 2 = 0.1 / 2 = 0.05 (mol).

Thus, the resulting amount of hydrogen substance:

v (H2) = 0.05 (mol).

Answer: 0.05 mol.
