See Below :)
Explanation:
15% NaOH by mass is 15g of NaOH in (100-15)g of solution.
No. Of moles of NaOH in solution = 0.65
No of moles of Water in solution = 4.72
Mole Fraction =
OR
= 0.65 / 5.37
= 0.121
PS - Calculated this as per 'What is the mole fraction of NaOH in an aqueous solution that contains 15.0% NaOH by mass?'
