We’re being asked to calculate the mole fraction of sucrose (C12H22O11in a solution that is prepared by dissolving 38.6 g sucrose (C12H22O11) in 495 g of water.

Sucrose (C12H22O11→ lesser in amount → solute
Water (H2O) → greater in amount → solvent

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

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