4.7 A sample of clay was obtained from a point below the groundwater table. A moisture con- tent test on this sample produced the following data: Mass of can = 10.88 g Mass of can+moist soil Mass of can+dry soil = 85.34 g = 116.02 g (a) Compute the moisture content. (b) Assume a reasonable value for G₁, and then compute the void ratio, unit weight, dry unit weight and buoyant unit weight.
