The Correct Option is C
Solution and Explanation
$0.06 \%\,( w / V )$ aqueous solution of urea $=\frac{0.06}{100}$
$=6 \times 10^{-4}\, g$
This means that $6 \times 10^{-4} \,g$ of urea is present in $1L$ of solution.
Molecular mass of urea
Molarity of urea solution
$=\frac{w \times 1000}{M \times \text { volume }( mL )} $
$=\frac{0.06 \times 1000}{100 \times 60}=0.01 \,M$
$\therefore 0.01 M$ glucose solution is isotonic with $0.06 \%$ (w/V) solution of urea.
$=6 \times 10^{-4}\, g$
This means that $6 \times 10^{-4} \,g$ of urea is present in $1L$ of solution.

Solutions
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.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
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.
