The answer is 5.1242x10^8
Answer:
The pH of solution is 2.88 .
Explanation:
The reaction is :
We know, 
for this reaction is = 
Also, since volume of water is 1 L.
Therefore, molarity of solution is equal to number of moles.
Also, ![K_a=\dfrac{[CH_3COO^-][H^+]}{[CH_3COOH]}](https://tex.z-dn.net/?f=K_a%3D%5Cdfrac%7B%5BCH_3COO%5E-%5D%5BH%5E%2B%5D%7D%7B%5BCH_3COOH%5D%7D)
Let, amount of 
produce is x.
So,
![K_a=\dfrac{[x][x]}{[0.1]}\\1.76\times 10^{-5}=\dfrac{[x][x]}{[0.1]}](https://tex.z-dn.net/?f=K_a%3D%5Cdfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B0.1%5D%7D%5C%5C1.76%5Ctimes%2010%5E%7B-5%7D%3D%5Cdfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B0.1%5D%7D)
We know, 
Therefore, pH of solution is 2.88 .
Hence, this is the required solution.
4.79 x 10⁻⁷moldm⁻³
Explanation:
Given parameters:
pOH of RbOH = 6.32
Unknown:
Molarity of the base = ?
Solution:
The pH or pOH scale is used for expressing the level of acidity alkalinity of aqueous solutions.
pOH = -log[OH⁻]
we know the pOH to be 6.32
6.32 = -log[OH⁻]
[OH⁻] = inverse log₁₀(6.32)
[OH⁻] = 4.79 x 10⁻⁷moldm⁻³

Answer:
The science. The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases
