Question

A solution contains 2 moles of ethyl alcohol and 3 moles of water calculate the mole friction of ethyl alcohol and water in this solution?​

Answer 1

Answer:

0.4

Explanation:

Given,

• Number of moles of ethyl alcohol = 2
• Number of moles of water = 3

To find,

• Mole fraction of the solution

Formula to calculate Mole fraction,Xi :-

• Xi = moles of solute/total number of moles of solute and solvent
• XI = 2/3+2
• Xi = 2/5
• Xi = 0.4
