$2-4.$ A $72-c{m}^3$ sample of moist soil weighs $141\mathrm{.}5g.$ When

it is dried out in an oven, it weighs $122\mathrm{.}7g.$ The spe$-$

cific gravity of solids is found to be $2\mathrm{.}66.$ Find the

water content, void ratio, porosity, degree of satura$-$

tion, and wet and dry unit weights.
