Question

In concentration of aqueous solutions find mass fraction and volume fraction using mole fraction 0.7304, specific gravity 0.6268, and molecular weight solute 42.00.

Answer 1

Volum fraction = 0.7304

Specific gravity of solute=0.6268

Molecular weight of solute=42.00

$Volume fraction=\frac{Mass \; fraction}{Specific \; gravity}\\ Mass fraction= Volum fraction \times Specific gravity \\ = 0.7304 \times 0.6268 \\ Mass fraction= 0.46 \\ Mole fraction = \frac{Mass \; fraction}{Mplecular weight}\\ = \frac{0.46}{42}$

Mole fraction= 0.01095
