Molecular weight of Ethanol is 46 And water is 18 .
No of moles of Ethanol } 23/46= 0.5
No of moles of Water } 36 /18 = 2
Mole fractions of Ethanol = No of moles of Ethanol / Total no of moles
n of Ethanol / n total = 0.5 / 2 + 0.5
0.5 / 2.5 = 0.2
Mole fractions of water will be
1 - mole fractions of Ethanol = 0.8.
