When table salt was heated with concentrated H2SO4, 224 g of HCL was obtained, how much salt reacted.

For the solution, let’s write down the data:

2NaCl + H2SO4 = Na2SO4 + 2HCl – ion exchange, sodium sulfate was formed;
Calculations by formulas:
M (NaCl) = 58.4 g / mol;

M (HCl) = 36.5 g / mol.

3. Let us determine the amount of acid, if the mass is known:

Y (HCl) = m / M = 224 / 36.5 = 6.14 mol;

Y (NaCl) = 6.14 mol since the amount of substances is 2 mol.

We find the mass of the original substance:
m (NaCl) = Y * M = 6.14 * 58.4 = 358.6 g

Answer: you need sodium chloride weighing 358.6 g
