One of the standard method of measuring specific gravity of solids uses a pycnometer. The pycnometer is first filled with water than it is refilled with a known mass of dry soil plus water so that the volume is the same as before. Using this method on a certain soil sample, the following data were obtained: Mass of soil = 81.8 g Moisture content of soil = 11.2% Mass of pycnometer plus water = 327.12 g Then mass of soil and water was refilled so that the volume is the same as before. Mass of pycnometer + soil + water = 373.18 g Volume of pycnometer = 250 ml a. Compute the specific gravity of this soil. b. Compute the degree of saturation if the void ratio is 0.54. c. Compute the air void ratio of the soi

pycnometer is first filled with water than it is refilled
with a known mass of dry soil plus water so that the
volume is the same as before. Using this method on
a certain soil sample, the following data were
obtained:
Mass of soil = 81.8 g
Moisture content of soil = 11.2%
Mass of pycnometer plus water = 327.12 g
Then mass of soil and water was refilled so that the
volume is the same as before.
Mass of pycnometer + soil + water = 373.18 g
Volume of pycnometer = 250 ml
a. Compute the specific gravity of this soil.
b. Compute the degree of saturation if the
void ratio is 0.54.
c. Compute the air void ratio of the soil.
