Question

whaT Will be the mole fraction of water in C2H5OH solution containing with equal no. of moles of water and C2H5OH

Answer 1

Ans will be 1/3 and 2/3

Answer 2

Answer: The mole fraction of water in $C_2H_5OH$ solution is0.5.

explanation:

Let the number of moles of water be x

Since, it is given that, solution contains equal moles of $H_2O&C_2H_5OH$.so,

The moles of $C_2H_5OH$ will also be x.

Mole fraction=$\chi_{H_2O}\frac{\text{moles of}H_2O}{\text{moles of }C_2H_5OH+\text{moles of}H_2O}$

$\chi_{H_2O}=\frac{x}{x+x}=\frac{x}{2x}=0.5$

Hence,the mole fraction of water in $C_2H_5OH$ solution is0.5.
