Question

AS A solution contains 1 mole of water and 4 mole of ethanol. The mole fraction of water
ethanol will be
(al 0.2 water + 0.8 ethanol
(b) 04 water + 0.6 ethanol
(c) 0.6 water + 0.8 ethanol
(d) 0.8 water .0.2 ethanol​

Answer 1

Answer:

a) 0.2 water + 0.8 ethanol

Explanation:

No. of moles of water = 1

No. of moles of ethanol = 4

Total no. of moles = 5

By Unitary Method

Mole Fraction of Water = 1/5 = 0.2

Mole Fraction of Ethanol = 4/5 = 0.8
