Given:
Dry density of soil = 1.5 g/cc
Saturation water content = 50%

To find:
Saturated density and submerged density of soil

Explanation:
Saturated density:
Saturated density is the density of the soil when all the voids are filled with water.

Saturated density = (1 + water content) x dry density

Given, water content = 50%
Dry density = 1.5 g/cc

Saturated density = (1 + 0.5) x 1.5
Saturated density = 2.25 g/cc

Submerged density:
Submerged density is the density of the soil when it is completely submerged in water.

Submerged density = (dry density) / (1 + void ratio)

We know that, void ratio = ((1/water content) - 1)

Given, water content = 50%
Void ratio = ((1/0.5) - 1) = 1

Submerged density = 1.5 / (1 + 1)
Submerged density = 0.75 g/cc

Therefore, the saturated density and submerged density of the soil are 2.25 g/cc and 0.75 g/cc respectively.

Answer:
c) 2.25 g/cc and 1.25 g/cc
