1. A soil sample has a weight of 125 grams and a volume of 55 cc in its natural state. If the degree of saturation is 55% and the unit weight of soil grains is 2.60 g/cc, what is the porosity? 2. A sample of sand above the water table was found to have a natural water content of 12% and a unit weight of 110 pounds per cubic foot. The unit weight of the soil grains was 2.64 g/cc. Calculate the void ratio and the degree of saturation. 3. The mass specific gravity of a soil sample is 1.70. The specific gravity of the soil grains is 2.65. What is the void ratio, assuming the sample is perfectly dry? 1. A soil sample has a weight of 125 grams and a volume of 55 cc in its natural state.
