72g
Explanation:
Given parameters:
Number of moles of LiOH = 3moles
Unknown:
Mass of LiOH = ?
Solution:
A mole of substance is a unit used to make quantitative measures in chemistry.
It is the amount of substance that contains the avogadro's number of particles.
The mole is related to mass using the expression below;
Mass of a substance = number of moles x molar mass
Molar mass of LiOH = 7 + 16 + 1 = 24g/mol
Mass of LiOH = 3 x 24 = 72g

The solubility of the compound is obtained as 9.5 * 10^-14 M.
<h3>What is the solubility product?</h3>
The solubility product refers to the equilibrium constant that shows the extent to which a thing is soluble in water, Now we can write the solubility product as;
Ksp = [Hg^2+] [2OH^-]^2
Let [Hg^2+] = [OH^-] = x
Then I can write;
Ksp = x * (2x)^2
Ksp = 4x^3
When x = solubility
x = ∛Ksp/4
Ksp = 3.60×10^−26
x = ∛ 3.60×10^−26/4
x = 9.5 * 10^-14 M

Answer:
The answer to your question is below:
Explanation:
1.- Atomic number, elements in the periodic table increase their atomic number from left to right.
2.- A weighted average of the masses of an element's isotopes.
3.- Most metals are brittle, Metals are not brittle, Non metals are brittle.
4.- Most reactive nonmetals, that is because halogens have 7 valence electrons that means that only need one electron to be stable.
5.- Amu, is the abbreviation of Atomic mass unit.
