$4\mathrm{.}4$ A sample of soil was compacted into a $\frac{1}{30}f{t}^3$ laboratory mold. The weight of the com$-$

pacted soil was $4\mathrm{.}1$ lb and its moisture content $13\mathrm{.}1\%.$ Using a specific gravity of solids of

$2\mathrm{.}70,$ compute the unit weight, dry unit weight and degree of saturation of this compacted

soil. This compacted soil sample was then submerged in water. After $2$ weeks, it was found

that the $lo{n}^{}$ sample had swelled and that its total volume had increased by $5\%.$ Compute the

new unit weight and moisture content of the soil sample after $2$ weeks of submersion in

water.
