The number of protons is the Atomic number
For the molarity and the percentage of the mass of kcl are mathematically given as
%m/m = 23.1%, molarity = 3.38M
<h3>What is the molarity?</h3>
Generally, the equation for the percentage of the mass of kcl is mathematically given as
(mass of kcl/mass of solution)x 100
therefore
%m/m = (6.31/27.29)x100
%m/m = 23.1%
The molarity
(no of mol/ vol of sol)
molarity = 0.0846mol/0.0250 L
molarity = 3.38M
In conclusion, the molarity is given as
molarity = 3.38M

The pH of the solution is a measure of the acidity of such solution. Acidity is the level of how much acid is present in a mixture and is associated with the concentration of hydronium ions. For pH, it is equal to the negative logarithm of the hydronium ion concentration. We use this to calculate for what was asked.
pH = - log [H+]
2.32 = - log [H+]
[H+] = 4.79x10^-3 M
