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

Sound waves are not a form of electromagnetic radiation
<span>Ksp = 1.2 x 10^-17 = [Zn2+] [OH-]^2
Zn(OH)2 <----> Zn2+ + 2OH-
[Zn2+] = x
[OH-] = 2x
1.2 x 10^-17 = (x) ( 2x)^2 = 4 x ^3
x = 1.4 x 10^-6 M
2x = 2.8 x 10^-6 M
pOH = - log 2.8 x 10^-6 = 5.5
pH = 14 - 5.5 =8.5
i think this is it
