Question

A solution contains 2mole of ethyl alcohol and 3mole of water, calculate mole fraction of ethyle alcohol and water in solution

Answer 1

Answer:

mole fraction of ethyl alcohol is 0.4 and water is 0.6

Explanation:

to find out the mole fraction, we divide the moles of component with the total moles of solution. In the question given above the total moles of solution are 5 moles (2+3=5). so, when we will divide 2 (moles of ethyl alcohol) with 5 we will get 0.4 and when we will divide 3 (moles of water) with 5 we will get the answer as 0.6.

Note: sum of mole fraction of solute and solvent is always equal to 1

for example, in the case given above, 0.4+0.6=1
