A sample of wet soil has a weight of 126 kg and a volume of 0.06 m³. The moisture content and the specific gravity of the soil solids are determined in the laboratory to be 15% and 2.7, respectively. Calculate the following: a. Moist unit weight (kN/m³), Moist density (g/cm³) b. Dry unit weight (kN/m³), dry density (g/cm³) d. Void ratio e. Porosity f. Degree of saturation (%)
