When `250 mg` of eugenol is added to `100 g` of camphor `(k_(f)=39.7" molality"^(-1))`, it lowered the freezing point by `0.62^(@)C` . The molar of eugenol is `:`

A

`1.6xx10^(2) g//mol`

B

`1.6xx10^(4)g//mol`

C

`1.6xx10^(3)g//mol`

D

`200g//mol`

Text Solution

Verified by Experts

The correct Answer is:
1

`0.62=(250xx10^(-3))/(Mxx100)xx1000xx39.7xx1`
`M=160` or `1.6xx10^(2)g//mol`

When 250 mg of eugenol is added to 100 g of camphor (K_(f) = 39.7K "molality"^(-1)) , it lowered the freezing point by 0.62^(@)C . The molar mass of eugenol is:

Addition of non-volatile solute to solvent lowers its vapoure pressure. Therefore, the vapour pressure of a solution (i.e, V.P. of solvent in a solution) is lower than that of pure solvent in a solution) is lower than that of pure solvent, at the same temperature. A higher temperature is needed to raise the vapour pressure upto one atmosphere pressure, when boiling point is attined. However, increase in b.pt. is small . for example, 0.1 molal aqueous sucrose solution boils at 10.05^(@)C Sea water, an aqueous solution, which is rich in Na^(+) and Cl^(-) ions, freezes about 1^(@)C lower than frozen water . At the freezing point of a pure-solvent, the reates at which two molecule stick together to form the solid and leave it to return to liquid are equal when solute is present. Few solvent molecules are in contact with surface of solid. However, the rate at which the solvent molecules leave, surface of solid remains unchanged. That is why, temperature is lowered to restore the equalibrium. The freezing depression in a dilute solution is proportional to molality of the solute. When 250 mg of eugonal is added to 100 g of camhor (K_(f) = 29.7 K "molality"^(-1)) . it lowered the freezing point by 0.62^(@)C . The molar mass of eugonal is :
