The Correct Option is A
Solution and Explanation
No. of moles of glucose $= \frac{10}{180} = 0.0555 \,mol$
No. of moles of water $= \frac{90}{18} = 5\,mol$
Number of moles of solution $= 5.0555\, mol$
Mole fraction of glucose $=\frac{\text{No. of moles of glucose}}{\text{No. of moles of solution}}$
$= \frac{0.0555}{5.0555} = 0.01$

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.
