Answer: The ![[OH^-]](https://tex.z-dn.net/?f=%5BOH%5E-%5D)
of a solution is 
M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of 
= 
Now put all the given values in the formula of molality, we get
pH or pOH is the measure of acidity or alkalinity of a solution.
According to stoichiometry,
1 mole of gives 1 mole of 
Thus 
moles of gives =
moles of
Putting in the values:
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[0.01][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5B0.01%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[OH^-]=10^{-12}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-12%7D)
Thus the of a solution prepared by dissolving 0.0912 g of hydrogen chloride in sufficient pure water to prepare 250.0 ml of solution is M
Answer:

Explanation:
Answer:
the answer is B: cue - white ball - blue ball.
Explanation:
The energy transfers from the stick to the white ball, then from the white ball to the blue ball. I also took this and it was correct!
Answer:
The answer to your question is below
Explanation:
3.-
[HF] = 6.9 N
Volume = ?
[H₃PO₄] = 3.2 N
Volume = 22ml
[HF] x Volume a = [H₃PO₄] x Volume b
Volume a = [H₃PO₄] x Volume b / [HF]
Volume a = 3.2 x 22 / 6.9
= 10.2 ml
4.-
[Al(OH)₃] = 4 N
Volume b = 72 ml
[HBr] = ?
Volume a = 21 ml
[Al(OH)₃] x Volume b = [HBr] x Volume a
[HBr] = [Al(OH)₃] x Volume b / Volume a
[HBr] = 4 x 72 / 21
[HBr] = 13.7 N
5.-
[HC₂H₃O₂] = 0.769 N
Volume a = ?
[Mg(OH)₂] = 1.15 N
Volume b = 31 ml
[HC₂H₃O₂] x Volume a = [Mg(OH)₂] x Volume b
Volume a = [Mg(OH)₂] x Volume b / [HC₂H₃O₂]
Volume a = 1.15 x 31 / 0.769
Volume a = 46.4 ml
X
Volume a = ?
[HCl] = 4.7 N
Volume b = 15.78 ml
[Ba(OH)₂] = 5.67 N
[HCl] x volume a = [Ba(OH)₂] x volume b
Volume a = [Ba(OH)₂] x volume b / [HCl]
Volume a = 5.67 x 15.78 / 4.7
Volume a = 19 ml
