Problem $14.$ The moist unit weights and degrees of saturation of a soil are given in the table:

$(k\frac{N}{m^3})S(\%)$

$16\mathrm{.}62,50$

$17\mathrm{.}71,75$

Determine:

a$.$ e $($void ratio$)$

b$.$ Gs $($specific gravity of soil solids$)$

Answers: $e=0\mathrm{.}81$; and $Gs=2\mathrm{.}66$
