Please help, i need help on problem #3. Please show all work so I can learn how to do it!
Extracted text: 3. Laboratory compaction test results on a clayey soil are listed in the table below. Moisture content (%) Dry unit weight (kN /m³) 6. 14.80 17.45 18.52 11 18.9 12 18.5 14 16.9 The following are the results of a field unit weight determination test on the same soil with the sand cone method: Calibrated dry density of Ottawa sand Calibrated mass of Ottawa sand to fill the cone = 0.505 kg Mass of jar + cone + sand (before use) = 8.59 kg Mass of iar + cone + sand (after use) = 4.38 kg Mass of moist soil from hole = 2.85 kg Moisture content of moist soil = 9.20 % 1560 kg/ m³ %3D Determine: a. Dry unit weight of compaction in the field. b. Relative compaction in the field.
