Some amount of urea is added to 1000 gm of H 2 O due to which vapor pressure decreases by 25% of the original vapor pressure. Find out the mass of urea added (Round off to two decimal places)

The correct answer is : 18.52 \(\frac{25}{75}=\frac{n_{urea}}{\frac{1000}{18}}\) \(\Rightarrow n_{urea}=\frac{1}{3}\times \frac{1000}{18}=18.52\)

A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.

For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.

The solutions can be classified into three types:

On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:

Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
