An irregular lump of saturated clay with a mass of 605.2 g was coated with paraffin wax. The total mass of the coated lump (in air) was 614.2 g. The volume of the coated lump was found to be 311 ml by displacement in water. After carefully removing the paraffin wax, the lump of clay was over-dried to a dry mass of 479.2 g. The specific gravity of the hardened wax is 0.90. Determine the water content, specific gravity, dry unit weight and void ratio.
