Answer:
1.4 × 10⁻⁴ M
Step-by-step explanation:
Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:
Molarity (M) = moles of solute/ liters of solution
Hydrochloric acid dissociates by the equation:
HCl = monoprotic acid, thus the concentration of the acid is the concentration of the hydronium ion.
[H⁺] is the hydrogen ion concentration in terms of molarity
[H⁺] is called hydronium ion.
HCl conc = 1.4 x 10⁻⁴ M
[H⁺] = 1.4 × 10⁻⁴ M
