We have that the Concentration of solution B is 2.5 times more than solution A's concentration.
<h3>UV(Ultra violent) rays</h3>
Question Parameters:
Upon UV-analysis, Solution B gave an absorbance of 1.0
Solution A gave an absorbance of 0. 4
Generally the equation for the Absorbance is mathematically given as
A = e*c*L
Therefore
For A solution
![0.4 = e*[cA]*L](https://tex.z-dn.net/?f=0.4%20%3D%20e%2A%5BcA%5D%2AL)
For B solution
![1.0 = e*[cB]*L](https://tex.z-dn.net/?f=1.0%20%3D%20e%2A%5BcB%5D%2AL)
Hence
![\frac{0.4}{ 1} = \frac{[cA]}{ cB}](https://tex.z-dn.net/?f=%5Cfrac%7B0.4%7D%7B%201%7D%20%3D%20%5Cfrac%7B%5BcA%5D%7D%7B%20cB%7D)
[cB] = 2.5 [cA]
Therefore
Concentration of solution B is 2.5 times more than solution A's concentration.

Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 0.66 mole/kg
