Answer : The vapor pressure of solution is 23.67 mmHg.
Solution:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
![\frac{p^o-p_s}{p^o}=\frac{w_2M_1}{w_1M_2}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%5Eo-p_s%7D%7Bp%5Eo%7D%3D%5Cfrac%7Bw_2M_1%7D%7Bw_1M_2%7D)
where,
= vapor pressure of pure solvent (water) = 23.76 mmHg
= vapor pressure of solution= ?
= mass of solute (sucrose) = 12.25 g
= mass of solvent (water) = 176.3 g
= molar mass of solvent (water) = 18.02 g/mole
= molar mass of solute (sucrose) = 342.3 g/mole
Now put all the given values in this formula ,we get the vapor pressure of the solution.
![\frac{23.76-p_s}{23.76}=\frac{12.25\times 18.02}{176.3\times 342.3}](https://tex.z-dn.net/?f=%5Cfrac%7B23.76-p_s%7D%7B23.76%7D%3D%5Cfrac%7B12.25%5Ctimes%2018.02%7D%7B176.3%5Ctimes%20342.3%7D)
![p_s=23.67mmHg](https://tex.z-dn.net/?f=p_s%3D23.67mmHg)
Therefore, the vapor pressure of solution is 23.67 mmHg.
Answer:
Air Pollution is the cause, air pollutants over the years weathered and eroded the Taj Mahal giving it a different color. But natural discoloration is normal since the Taj Mahal is over 400 years old.

Answer:
Chemistry definition: Concentration Definition. In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.
Dictionary Definition: the action or power of focusing one's attention or mental effort
