Please kindly answer all. C and d answers mandatory. Please answer all and help me.. thank you
A Standard Proctor compaction test was conducted on the soil, with the results shown below. The weight and volume of the mold used in the test were 4.6 lb and 1/30 ft3, respectively, and the mass of the can was 44 grams. Based on the results: Determine the optimum water content and maximum dry unit weight for the borrow soil. Determine the unit weight required for 95% of maximum, and what the range of moisture content for that unit weight is. The sample with the lowest water content was tested for its densest void ratio, which was 0.05, and its loosest void ratio, which was 0.55. Determine its relative density
