A gray silty clay (CL) is sampled from a depth of 12.5 feet. The "moist" soil was extruded ffrom a 6-inch high brass liner with an inside diameter of 2.83 inches and weighed 777 grams.
(a) Calculate the wet unit weight in pounds per cubic feet.
(b) A small chunk of the original sample had a weight of 140.9 grams and weighed 85.2 grams after drying. Compute the water content, using the correct number of significant figures.
(c) Compute the dry density in Mg/m^3 and the dry density unit weight in kN/m^3.
