Question

Calculate mole fraction of solute and solvent having 15% of ethanol

Answer 1

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%
