Pls help ASAP on this question. Q2. The in-situ (on site) gravimetric water content, void ratio, and specific gravity of a soil are19.5%, 0.68, and 2.65, respectively. Determine the bulk density, dry density, and degree of saturationof the soil. An undisturbed sample of this soil having a total volume = 200 cm³ is obtained fromthe site and is subjected to water infiltration in a laboratory test. At the end of water infiltration,the sample's gravimetric water content was found to be equal to 40.2% and its total volume wasfound to have increased by 30%. Estimate the degree of saturation of the soil sample after waterinfiltration and establish if the sample has reached full saturation or not. If the sample was notpermitted to change its total volume during water infiltration, what would have been its gravimetricwater content at full saturation?
