The molar mass of sugar in the given solution is to be determined. Concept introduction: Osmosis is the diffusion of a fluid through a semipermeable membrane. When a semipermeable membrane (animal bladders, skins of fruits and vegetables) separates a solution from a solvent, then only solvent molecules are able to pass through the membrane. The osmotic pressure of a solution is the pressure difference needed to stop the flow of solvent across a semipermeable membrane. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution. Osmotic pressure and molarity of the solute in the solution are directly proportional. and can be calculated by the formula: M = π R T

Chapter 13, Problem 102AP

Interpretation Introduction

Interpretation:

The molar mass of sugar in the given solution is to be determined.

Concept introduction:

Osmosis is the diffusion of a fluid through a semipermeable membrane.

When a semipermeable membrane (animal bladders, skins of fruits and vegetables) separates a solution from a solvent, then only solvent molecules are able to pass through the membrane.

The osmotic pressure of a solution is the pressure difference needed to stop the flow of solvent across a semipermeable membrane.

The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution.

Osmotic pressure and molarity of the solute in the solution are directly proportional.

and can be calculated by the formula:

M=πRT
