According to one acid-base theory, a water molecule acts as an acid when the water molecule (3) donates an H+.
The concentration of the HCl solution is 0.72 M.
<h3>How do we calculate the concentration?</h3>
Concentration of the required solution by the use of the known concentration solution will be determine by using the below equation as:
M₁V₁ = M₂V₂, where
- M₁ & V₁ are the molarity and volume of the HCl solution.
- M₂ & V₂ are the molarity and volume of the NaOH solution.
On putting values in the above equation, we get
M₁ = (1)(0.018) / (0.025) = 0.72 M
Hence required concentration of HCl is 0.72M.

Answer:
More than 40 percent measured above 5 ppb of lead, which the researchers considered an indication of a “very serious” problem.
Given the speed, you will travel 195km in 3 hours.
65 x 3 = 195
