It is needed to determine the moist unit weight of the soil for field compaction testing. A silty soil sample has a mass of 612 grams. The soil sample was then covered in beeswax and the combined weight was 650 g. The soil covered in wax, was then immersed in the water and the graduated cylinder registered a volume difference of 404 ml. The wax was gently peeled off the soil. Moisture content = 12% Specific Gravity = 2.78 But if the wax has a specific gravity of 0.94, determine the following: Dry unit weight of the soil Void ratio of the soil % of air in relation to the soil solids of the sample
