The "chunk density" method is often used to determine the unit weight of a specimen of irregular shape. A specimen of cemented silty sand is treated in this way to obtain the "chunk density." From the information given below, determine the

(a) Wet density

(b) Dry density

(c) Void ratio

(d) Degree of saturation of the sample.

Mass of specimen at natural water content in air = 181.8 g

Mass of specimen + wax coating in air = 215.9 g

Mass of specimen + wax in water = 58.9 g

Natural water content = 2.5%

Soil solid density = 2650 kg/m3

Wax solid density = 940 kg/m3
