What volume of hydrogen will be obtained by reacting 50 g of acetic acid with sodium?

1. The interaction of acetic acid with sodium proceeds according to the equation:

2CH3COOH + 2Na → 2CH3COONa + H2 ↑;

2.Calculate the chemical amount of acetic acid:

n (CH3COOH) = m (CH3COOH): M (CH3COOH);

M (CH3COOH) = 12 + 3 + 12+ 32 + 1 = 60 g / mol;

n (CH3COOH) = 50: 60 = 0.8333 mol;

3. according to the reaction equation, 2 mol of acid gives 1 mol of hydrogen, we find the amount of hydrogen released:

n (H2) = n (CH3COOH): 2 = 0.8333: 2 = 0.4167 mol;

4. find the volume of hydrogen:

V (H2) = n (H2) * Vm = 0.4167 * 22.4 = 9.334 l.

Answer: 9.334 liters.
