A gray silty clay (CL) is sampled from a depth of 12.5 feet.The "moist"soil was extruded from a 6-inch-high brass liner with an inside diameter of 2.83 inches and weighed 777 grams.
a) Calculate the wet density in pounds per cubic feet.
b) A small chunk of the original sample had a wet 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/m3 and the dry unit weight in kN/m3.
