Q.1: 2. Calculate the Porosity and Bulk volume of a dry core sample immersed in mercury pycnometer, given the following data: Weight of dry sample in air: 20 gm, Weight of mercury-filled pycnometer : 350 gm, Weight of mercury-filled pycnometer with the sample ; 235.9 gm. Density of mercury: 13.546 gm/cc.

3. The dissolved solids content is determined by filtering a portion of the sample through a glass fiber filter disc into a porcelain evaporating dish, drying the sample at 100°C, and igniting the residue by placing the dried sample in a muffle furnace at 550°C. The following masses are recorded: *Volume of sample: 25 mL •Mass of empty dish: 51.494 g a) The total dissolved solids content is: •Mass of dish and dried solids: 51.524g •Mass of dish and ignited solids: 51.5069 g b) The volatile dissolved solids content is: Does the total solids content equal the sum of the suspended and dissolved solids? c) The fixed dissolved solids content is:

True False

The total mass of a sample is 102.40 g, the total volume is 48.00 cm3, the water content is 20.00%, and the relative density (relative density of the solids) is 3.20. Find the total density (ρ), dry densoty (ρD), and the void ratio (e).
