Chapter U3.18, Problem 3E

Interpretation Introduction

Interpretation:

The maximum vapor density possible at 30 degree Celsius must be explained.

Concept introduction:

Vapor density depends on temperature. Saturated vapor density is the maximum amount of vapor air can hold at a particular temperature.

Answer to Problem 3E

1.7 mol/1000 L.

Explanation of Solution

Maximum vapor density possible for air depends on the place and temperature. At higher temperature more water vapor is required to make saturation of air by water vapor.

The water vapor density versus temperature plot is represented as follows:

From the above plot, at 30 ^oC, the water vapor density is approximately 1.7 mol/1000 L.
