Chapter 14, Problem 84AE

(a)

Interpretation Introduction

Interpretation:

Mass of ethylene glycol added to 12.0 L of water in automobile radiator to protect it from freezing at 20 °C has to be determined.

Concept Introduction:

Colligative properties are dependent on amount of solute and not on their natures. These are caused due to addition of nonvolatile solute in any solution. Below mentioned are colligative properties.

1. Freezing point depression

2. Boiling point elevation

3. Vapor pressure lowering

4. Osmotic pressure

(b)

Interpretation Introduction

Interpretation:

Volume of ethylene glycol added to 12.0 L of water in automobile radiator to protect it from freezing at 20 °C has to be determined.

Concept Introduction:

Density of substance is ratio of mass per unit volume. Expression for density of substance is as follows:

  Density of substance=Mass of substanceVolume of substance

(c)

Interpretation Introduction

Interpretation:

Temperature in Fahrenheit that will protect radiator has to be determined.

Concept Introduction:

Temperature is quantity of substance that measures hotness or coldness. It can be measured in Kelvin, Celsius and Fahrenheit.
