Answer:

23 g of ethanol = 0.5 mole

36 g of water = 2 mole

molefraction of solute = number of moles of solute / total number of moles

molefraction of ethanol = 0.5/0.5 +2 = 0.5 / 2.5  = 0.2

Answer:

Mole fraction of ethanol is equal to 0.2

Explanation:

Moles of ethanol is equal to 23/46= 0.5

And moles of water is equal to 36/18= 2

therefore

Mole fraction of ethanol=moles of ethaol/total moles.

Mole fraction of ethanol = 0.5/2.5 =0.2
