Quizplus · Accepted Answer

The void ratio of a 200 gram soil sample with an 80% degree of saturation and a moisture content of 20.5% is 67%.
Solution: Use the following equation to determine the void ratio, e
e = Specific gravity x moisture content / degree of saturation
= GS x W / S
Given specific gravity, GS = 2.6
moisture content, W = 20.5 %
degree of saturation, S = 80%
Therefore, e = [(2.6 x 20.5) / 80] x 100
e = 67%
