The concentration of the HI solution is 0.75M.
<h3>How do we calculate the required concentration?</h3>
Required concentration of any solution used in titration will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
M₁ & V₁ are the molarity and volume of CsOH.
M₂ & V₂ are the molarity and volume of HI.
On putting all values from the question, we get
M₂ = (1.9)(9.9) / (25) = 0.75M
Hence required concentration of HI solution is 0.75M.

The Ka equation
Answer:
When electrons move from a higher energy level to a lower one, photons are emitted, and an emission line can be seen in the spectrum. Absorption lines are seen when electrons absorb photons and move to higher energy levels. ... An atom in its lowest energy level is in the ground state.
The height of the bin is 29.9m.
The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
The total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.
The radius of the cylinder, r = 5m
Surface area = 1099 m²
∴ A = 2πrh + 2πr²
Therefore, the height of the bin is 29.9m.
