Can you please only answer B & C. Show clear work please so I can understand the concept!
Extracted text: Standard Proctor test was conducted on a silty clay soil collected from a proposed construction site. The results are shown in the following table. mass of moist soil in the mold (g) Dry density trial no. moisture content (%) 1 1480 9.4 2 1570 12.4 3 1690 14 4 1700 15.5 1650 18.3 a. Determine the maximum dry density (kg/m3) of compaction and the optimum moisture content. Given: volume of mold: 943.3 cm3. b. What is the degree of saturation at optimum moisture content? Gs=2.75 c. If the required field dry unit weight is 1470 kg/m3, what is the relative compaction? d. What should be the range of compaction moisture contents in the field to achieve the above relative compaction?
