Answer 2

Answer is 0.025%

Ethyl alcohol (C2H6O) with water (H2O)

Molar mass of ethyl alcohol is 46 and water is 18

Moles = mass/ molar mass

Moles of ethyl alcohol=46/46= 1

Moles of water = 54/18=3. (100-46=54)

Total moles =1+3=4

Mole fraction of ethanol is Mole of ethanol/ Total mole of solution =1/4=0.25
