Answer:0.068
Explanation:here 20% means 20g ethyl glucol in 100g solution. so we got the given mass.Next calculate the molar mass of ethyl glucol that is 2*12+1*6+16*2=62
so lets calculate the number of moles of ethyl glycol from the findings:20/62=o.322 moles
no of moles of water=80/18=4.444
hence mole fraction of ethyl glycol =0.322/0.322+4.444=0.068
