Answer to Question #245729 in General Chemistry for Naomi

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
