How much hydrogen chloride must be passed through 100 ml of water to obtain an 8% hydrochloric

How much hydrogen chloride must be passed through 100 ml of water to obtain an 8% hydrochloric acid solution? Enter the volume of hydrogen chloride (in liters), to the nearest tenth.

Answer: V = 5.4 liters.
Explanation of the solution to the problem: to solve this problem, you must use the following formula:
w = m (solv.v-va) / m (solution), where w is the mass fraction of the solute in the solution, m (solv.v-va) is the mass of the solute, m (solution) is the mass of the solution …
Let the mass of hydrogen chloride be m. Then we get:
0.08 = m / (100 + m)
Hence m = 8.696 g.
Now we find the amount of hydrogen chloride substance:
n = m / M = 8.696 / 36.5 = 0.24 mol.
The last step is to find the volume of hydrogen chloride:
V = n * Vm = 0.24 * 22.4 = 5.4 liters.
