Chapter 12, Problem 11SAQ

Interpretation Introduction

Interpretation:

The osmotic pressure of a solution containing $22.7\text{mg}$ of an unknown protein in $50.0\text{mL}$ of solution at $25°\text{C}$ is $2.88\text{mm}\text{Hg}$ . The molar mass of the protein is to be calculated.

Concept Introduction: The osmotic pressure of solution is calculated by the formula,
  $\Pi =M\text{R}T$

To determine: The molar mass of the protein.

Correct answer: The correct option is (c).
