Question

Use the diagram to determine the boiling point of each liquid

Answer 1

Step-by-step explanation:

We first convert the given pressures to one consistent with that of the scale used in the plot of the graph.

The main conversion from mmHg to kPa:

1mmHg = 0.1333kPa:

For 600mmHg will be 80kPa of chloroform

400mmHg of ethanol will be 53.3kPa

400mmHg of water will be 53.3kPa

Now to find the boiling points, trace the pressure from the vertical axis till it intersects the respective curve of each compound.

For chloroform, we obtain 52°C

water gives 82°C

ethanol gives 62°C
