<u>Answer:</u> The freezing point of solution is 2.6°C
<u>Explanation:</u>
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,
![\Delta T_f=i\times K_f\times \frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ in grams}}](https://tex.z-dn.net/?f=%5CDelta%20T_f%3Di%5Ctimes%20K_f%5Ctimes%20%5Cfrac%7Bm_%7Bsolute%7D%5Ctimes%201000%7D%7BM_%7Bsolute%7D%5Ctimes%20W_%7Bsolvent%7D%5Ctext%7B%20in%20grams%7D%7D)
where,
= ![\text{Freezing point of pure solution}-\text{Freezing point of solution}](https://tex.z-dn.net/?f=%5Ctext%7BFreezing%20point%20of%20pure%20solution%7D-%5Ctext%7BFreezing%20point%20of%20solution%7D)
Freezing point of pure solution = 5.5°C
i = Vant hoff factor = 1 (For non-electrolytes)
= molal freezing point depression constant = 5.12 K/m = 5.12 °C/m
= Given mass of solute (anthracene) = 7.99 g
= Molar mass of solute (anthracene) = 178.23 g/mol
= Mass of solvent (benzene) = 79 g
Putting values in above equation, we get:
![5.5-\text{Freezing point of solution}=1\times 5.12^oC/m\times \frac{7.99\times 1000}{178.23g/mol\times 79}\\\\\text{Freezing point of solution}=2.6^oC](https://tex.z-dn.net/?f=5.5-%5Ctext%7BFreezing%20point%20of%20solution%7D%3D1%5Ctimes%205.12%5EoC%2Fm%5Ctimes%20%5Cfrac%7B7.99%5Ctimes%201000%7D%7B178.23g%2Fmol%5Ctimes%2079%7D%5C%5C%5C%5C%5Ctext%7BFreezing%20point%20of%20solution%7D%3D2.6%5EoC)
Hence, the freezing point of solution is 2.6°C
The difference between an organ and a tissue is that basically tissues are a group of similar cells that works together. Then a group of tissue that works together would make up an organ. Groups of organ working together later makes up an organ system. This is the main difference between an organ and a tissue.
They have the most moons because they have the most mass
