Question

A solution contains 36.0 g Water and 46.0 g ethyl alcohol . Determine the mole fraction of each component in the solution.

Answer 1

moles of water(nw)= 36/18=2
moles of ethyl alcohol(ne)=46/46=1
total moles=2+1=3
mole fraction of water =2/3=.66
mole fraction of ethyl alcohol =1-0.66=.44
