A 72 cm3 sample of moist soil weights 141.5 g. When it is dried out in an oven, it weighs 122.7 g. The specific gravity of solids is found to be 2.66. After you detrmine the water content, void ratio, porosity, degree of saturation; the wet unit weight would be:

1. 19.30 kN/m3

2. 15 kN/m3

3. 16 kN/m3

4. 21 kN/m3

pls find the option
