A solution is prepared by dissolving 38.6 g sucrose (C12H22O11) in 495 g of water. Determine the mole fraction of sucrose if the final volume of the solution is 508 mL. Group of answer choices

Explanation:

Hello!

In this case, since the mole fraction relates the moles of solute and the moles of solution, and for sucrose it is:

Whereas we need to compute the moles of both sucrose and water based on their molar masses (342.3 and 18.02 respectively) as shown below:

Thus, the mole fraction sucrose turns out:
