During the completion of a construction project, a soil sample was taken from an area of compacted earth fill for a sand-cone in-place density test. The following were obtained from the results of the test: • Weight of sand used to fill the test hole and the funnel of the sand-cone device = • Weight of sand to fill the funnel of the sand-cone device • Unit weight of sand = 15.71 kN/m³ 845 g 323 g Weight of wet soil excavated from test hole = 622 g %3D • Moisture content of the soil excavated from the test hole = 16% Calculate the dry unit weight (kN/m³) of the excavated material

1.4 A test for the relative density of soil in place was performed by digging a small hole in the soil. The volume of the hole was 400 ml and the moist weight of the excavated soil was 9 N. after oven drying, the weight was 7.8 N. Of the dried soil, 4N was poured into a vessel in a very loose state, and its volume was found to be 270 ml. The same weight of soil when vibrated and compacted had a volume of 200 ml. Determine the relative density.
