Question

The mole fraction of ethyl alcohol in a solution containing 46 g of ethyl alcohol in 180 g of water is

Answer 1

Explanation:

find number of moles. then mole fraction

Answer 2

Answer:

Explanation:

mole fraction of solute= moles of solute/ moles of solute + moles of sovent

moles of solute( ethyl alcohol) = mass given/ molar weight

                                                  = 46/46

                                                  =1

moles of solvent(water) = 180/18

                                       = 10

mole fraction of ethyl alcohol = 1/1 + 10

                                                =1/11

                                               =0.09

∴ the mole fraction of ethyl alcohol is 0.09

I HOPE THIS IS HELPFUL
