Task $1\mathrm{.}1$ Calculate basic physical$-$mechanical characteristics of the soil

A damp silty clay soil sample weighing $150kg$ was collected and the material was tested in a soil laboratory, the following data were obtained: Water content, $w=15\%,$ wet density $=2000k\frac{g}{m^3},$ and specific gravity $(Gs)=2\mathrm{.}7.$

Determine the following properties of the soil: $($i$)$ dry density, $($ii$)$ porosity; $($iii$)$ void ratio; and $($iv$)$ Degree of saturation.
