The "chunk density" method is often used to determine the unit weight (and other necessary Information) of a specimen of irregular shape, especially of friable samples. The specimen at its natural water content is
(I) weighed,
(2) painted with a thin coat of wax or paraffin (tn prevent water from entering the porn),
(3) weighed again (H; + WW), and
(4) weighed in water (to get the volume of the sample + wax coating remember Archimides?). Finally, the natural water content of the specimen is determined. A specimen of 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, and
(d) degree of saturation of the sample.
