Chapter 17, Problem 117AE

Interpretation Introduction

Interpretation:

The mass percent of MgCl₂ in a solid mixture containing MgCl₂ and NaCl needs to be deduced under the given conditions

Concept Introduction:

• Osmosis refers to the net flow of solvent molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration.

• Osmotic pressure (p) is the difference in pressure across a concentration gradient. It is directly proportional to the molarity (M) of a solution.
$\text{π = iMRT -----(1)}$

Where R = gas constant and T = temperature

i = Von’t Hoff factor which is the number of ions per mole of solute dissolved in a given

solvent
