Answer 2

Given:

Solution of urea has been prepared by dissolving 6 gram of urea in 500 grams of water.

To find:

Depression in freezing point of the solution.

Calculation:

Depression in freezing point be denoted as ∆T.

$\sf{ \therefore \: \Delta T = i \times K_{f} \times m}$

$\sf{ = > \: \Delta T = 1 \times 1.86 \times \bigg \{ \dfrac{ (\frac{6}{60}) }{500} \times 1000 \bigg \}}$

$\sf{ = > \: \Delta T = 1 \times 1.86 \times \bigg \{ \dfrac{ (\frac{1}{10}) }{5 \cancel{00}} \times 10 \cancel{00 }\bigg \}}$

$\sf{ = > \: \Delta T = 1.86 \times \bigg \{ \dfrac{ (\frac{1}{10}) }{5 \cancel{00}} \times 10 \cancel{00 }\bigg \}}$

$\sf{ = > \: \Delta T = 1.86 \times \dfrac{1}{5} }$

$\sf{ = > \: \Delta T = 0.372 \: \degree C }$

So , the final answer is :

$\boxed{ \green{ \sf{ \large{\: \Delta T = 0.372 \: \degree C }}}}$
