1. In order to determine the density of a clay soil an undisturbed sample was taken in a sampling tube of volume $0.001664{\mathrm{m}}^3$. The following data were obtained: Mass of tube (empty) $=1.864\mathrm{kg}$ Mass of tube and clay sample $=5.018\mathrm{kg}$ Mass of tube and clay sample after drying $=4.323\mathrm{kg}$ Calculate the water content, the bulk, and the dry densities. If the particle specific gravity was 2.69 , determine the void ratio and the percentage saturation of the clay. (Show all calculations) 2. A soil sample has a weight of $0.7\mathrm{kg}$ and the volume was found to be $3.5\times 10?4{\mathrm{m}}^3$. After oven drying overnight, the weight was reduced to $0.6\mathrm{kg}$. The particle specific gravity (Gs) test yielded a result of 2.6. Determine the following: (Show all calculations) - Moisture Content - Dry Density - Bulk Density - Void ratio - Porosity - Saturation
