5.85g (NaCl) reacts with H2SO4, determine the volume of hydrogen chloride evolved.

1. Let’s compose the reaction equation:

2NaCl + H2SO4 = Na2SO4 + 2HCl ↑;

2.Calculate the chemical amount of sodium chloride:

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

M (NaCl) = 23 + 35.5 = 58.5 g / mol;

n (NaCl) = 5.85: 58.5 = 0.1 mol;

3.Set the chemical amount of hydrogen chloride released:

n (HCl) = n (NaCl) = 0.1 mol;

4.determine the volume of hydrogen chloride:

V (HCl) = n (HCl) * Vm = 0.1 * 22.4 = 2.24 liters.

Answer: 2.24 liters.
