Question

A solution contain ethanol and water the mole fraction of ethonal and water in the solution are 1/5 and 4/5 respectively the mole percentage of ethomal is

Answer 1

Answer:20%

Explanation:

mole fraction= moles of ethanol/total no. of moles

here, moles of ethanol is 1,

                  and total moles are 5

mole % = moles of ethanol/total no. of moles *100
