Q.1(a) In a natural state, a moist soil has a volume of 0.0088 m’ and a mass of 17.8 kg. After oven dry, the soil has a mass of 16.12 kg. If the specific gravity of the soil is 2.6, determine the following properties of the soil: (i) mass of water (Mw); (ii) moisture content (w); (iii) bulk density ((Pb); (iv) dry density (Pdry); (v) volumes of air (Va), water (VW) and solid grain (Vs); (vi) air void ratio (Av); (vii) void ratio (e); (viii) porosity (n); (ix) degree of saturation (S.); (x) additional water mass required to achieve 100% saturation of the soil; (xi) saturated density (Psat); and (xii) submerged density (Psub).

It is in a saturated state with moisture content of 25 % and specific gravity of 2.69. Determine the following properties of this soil: (i) void ratio (e); (ii) porosity (n); (iii) saturated density (Psat); (iv) dry density (Pdry); (v) saturated unit weight (Ysat); and (vi) density of soil solid grain (ps).
