A solution contains 0.066 moles of methanol, 0.603 moles of ethanol and 3.85 moles of water. what is the mole fraction of each componet in solution? ethanol, methanol, water.

Solution

total number of moles = 0.066 + 0.603 + 3.85

= 4.519

mole fraction of ethanol = 0.603 / 4.519

= 0.133

mole fraction of methanol = 0.066 / 4.519

= 0.0146 on rounding off we get 0.015

mole fraction of water = 3.85 / 4.519

= 0.852
