An undisturbed soil sample was collected in a sampling tube of internal diameter 5cm. The length of the extracted sample was 10.2 cm and its mass was 360 g. After oven drying the mass reduced to 326.5 g. The specific gravity was determined to be 2.70. Find the following:
a) Dry unit weight of the sample
b) Water content
c) Void ratio
d) Degree of saturation
e) Mass of water to be added to the sample to reach full saturation
