Please answer the question below. It would be a big help. Thank you. Please be clear with your answer. Box the final answer. Given the following characteristics of a soil sample: Volume = 0.5 ft3Mass = 56.7 lbThe solids specific gravity of 2.69. After oven drying, the mass of the soil has 48.7 lbs.a) What is the density of the in-situ soil?b) What is the porosity of the in-situ soil?c) What is the degree of saturation of the in-situ soil?
Plot sieve size (x-axis) against % finer. Calculate for D60mm, D30mm and D10mm. Find the percentage of gravel, sand and fines. Find the CU (Coefficient of uniformity) and CC (coefficient of curvature).

Geotechnical Engineering Please help me answer this question, and please show your solutions write it properly. Problem 3 A soil sample with a grain specific gravity of 2.67 was filled in a 1000mL container in the loosest possible state and the dry unit weight of the sample was found to be 14.75 N. It was then filled at the densest obtainable state and the weight was found to be 17.70 N. The void ratio of the soil in the natural state was 0.63. Determine the relative density in the natural state.
