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.
