Explanation:
15g of ethanol is present in 100g of water.
water = solvent and ethanol = solute.
therefore, finding mole fraction:
Xe = no of moles of ethanol
_________________________________
no of moles of ethanol +no of moles of water
xe =
0.3260
_______×100%
5.0482
= 6.4%
Xw = no of moles of water
_________________________________
no of moles of ethanol +no of moles of water
= 4.7222
________×100%
5.0482
= 93.54%
