Problem: Using the graph,determine the following.The approximate vapor pressure of CS2 at 30 oC.

FREE Expert Solution

We are asked to approximate the vapor pressure of CS2 at 30°C using the graph below:

The x-axis is temperature (degrees C) ranging from negative 30 to 50 with intervals of 20. The y-axis is vapor pressure (torr) ranging from 0 to 800 with intervals of 100. The data are described in the table below; values are approximate.  At -30 degrees Celsius, vapor pressure is 30 torrs.  At -10 Celsius, 90 torr, 10 Celsius is 200 torr, 30 Celsius is 400 torr and 45 Celsius is 800 torr.
