We’re being asked to calculate the mole fraction of sucrose (C_{12}H_{22}O_{11}) in a solution that is prepared by dissolving 38.6 g sucrose (C_{12}H_{22}O_{11}) in 495 g of water.

**Sucrose (C _{12}H_{22}O_{11}) **→ lesser in amount → solute

*Mole Fraction (X)** relates the moles of solute and solvent within a solution:*

$\overline{){\mathbf{m}}{\mathbf{o}}{\mathbf{l}}{\mathbf{e}}{\mathbf{}}{\mathbf{f}}{\mathbf{r}}{\mathbf{a}}{\mathbf{c}}{\mathbf{t}}{\mathbf{i}}{\mathbf{o}}{\mathbf{n}}{\mathbf{}}{\mathbf{\left(}}{\mathbf{X}}{\mathbf{\right)}}{\mathbf{=}}\frac{\mathbf{m}\mathbf{o}\mathbf{l}\mathbf{e}\mathbf{}\mathbf{o}\mathbf{f}\mathbf{}\mathbf{s}\mathbf{o}\mathbf{l}\mathbf{u}\mathbf{t}\mathbf{e}}{\mathbf{m}\mathbf{o}\mathbf{l}\mathbf{e}\mathbf{}\mathbf{o}\mathbf{f}\mathbf{}\mathbf{s}\mathbf{o}\mathbf{l}\mathbf{u}\mathbf{t}\mathbf{i}\mathbf{o}\mathbf{n}}}$

**We’ll calculate the mole fraction of sucrose using the following steps:**

A solution is prepared by dissolving 38.6 g sucrose (C_{12}H_{22}O_{11}) in 495 g of water. Determine the mole fraction of sucrose if the final volume of the solution is 508 mL.
