need help with number 2 please

Problem 2 A. An in-place field density test is conducted on a lift of embankment soil. The weight of moist soil excavated from a hole is 12.18 lbs. The hole's volume measured with sand cone is 0.095cuft. A representative water content sample of 112.5 grams of soil weighs 95.0 grams after oven drying. Determine the dry unit weight and moisture content of excavated soil. B. A bulk sample of material is taken back to the lab to obtain a Standard Proctor compaction curve. The data for the curve is given below: (The volume of the compaction mold =1/30cu.ft ) a. Plot the compaction curve. b. Identify (on your curve) and report maximum dry unit weight and optimum water contents. c. What is the degree of saturation S at this peak point if Gs is 2.65 ? d. Show (plot the window for) the following specs on your compaction curve: RC> 95% and the range of water content is +2% and 2%
