Chapter 12, Problem 9SAQ

Interpretation Introduction

Interpretation:

The amount of glucose that should be dissolved in $10.0\text{kg}$ of water to obtain a solution with a freezing point of $-4.2°\text{C}$ is to be calculated.

Concept Introduction: The depression in freezing point is calculated by the formula,
  $\Delta T_{\text{f}}=\frac{x}{M_{\text{G}}\times M_{\text{W}}}\times K_{\text{f}}$

To determine: The amount of glucose that should be dissolved in $10.0\text{kg}$ of water to obtain a solution with a freezing point of $-4.2°\text{C}$ .

Correct answer: The correct option is (b).
