<u>Answer:</u> The freezing point of solution is 5.35°C
<u>Explanation:</u>
The equation used to calculate depression in freezing point follows:
![\Delta T_f=\text{Freezing point of pure solution}-\text{Freezing point of solution}](https://tex.z-dn.net/?f=%5CDelta%20T_f%3D%5Ctext%7BFreezing%20point%20of%20pure%20solution%7D-%5Ctext%7BFreezing%20point%20of%20solution%7D)
To calculate the depression in freezing point, we use the equation:
![\Delta T_f=iK_fm](https://tex.z-dn.net/?f=%5CDelta%20T_f%3DiK_fm)
Or,
![\text{Freezing point of pure solution}-\text{Freezing point of solution}=i\times K_f\times \frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ (in grams)}}](https://tex.z-dn.net/?f=%5Ctext%7BFreezing%20point%20of%20pure%20solution%7D-%5Ctext%7BFreezing%20point%20of%20solution%7D%3Di%5Ctimes%20K_f%5Ctimes%20%5Cfrac%7Bm_%7Bsolute%7D%5Ctimes%201000%7D%7BM_%7Bsolute%7D%5Ctimes%20W_%7Bsolvent%7D%5Ctext%7B%20%28in%20grams%29%7D%7D)
where,
Freezing point of pure solution = 5.5°C
i = Vant hoff factor = 1 (For non-electrolytes)
= molal freezing point elevation constant = 4.90°C/m
= Given mass of solute (naphthalene) = 2.60 g
= Molar mass of solute (naphthalene) = 128.2 g/mol
= Mass of solvent (benzene) = 675 g
Putting values in above equation, we get:
![5.5-\text{Freezing point of solution}=1\times 4.90^oC/m\times \frac{2.60\times 1000}{128.2g/mol\times 675}\\\\\text{Freezing point of solution}=5.35^oC](https://tex.z-dn.net/?f=5.5-%5Ctext%7BFreezing%20point%20of%20solution%7D%3D1%5Ctimes%204.90%5EoC%2Fm%5Ctimes%20%5Cfrac%7B2.60%5Ctimes%201000%7D%7B128.2g%2Fmol%5Ctimes%20675%7D%5C%5C%5C%5C%5Ctext%7BFreezing%20point%20of%20solution%7D%3D5.35%5EoC)
Hence, the freezing point of solution is 5.35°C

Answer:
shear walls, cross braces, diaphragms, and moment-resisting frames are central to reinforcing a building. Shear walls are a useful building technology that helps to transfer earthquake forces. Made of panels, these walls help a building keep its shape during movement.
