Solution:

A mass of soil coated with a thin layer of paraffin wax weighs 650 g, and the soil alone weighs 600 g. When the soil sample is immersed in water, it displaces 400 ml of water. The specific gravity of the soil is 2.67, and the specific gravity of the wax is 0.9. The water content of the soil is 20%. The void ratio of the soil is:

0.841

0.481

0.624

0.462
