The moisture content $($w$)$ of a soil sample is $18\mathrm{.}6\%$ and its dry unit weight $(\backslash$gamma d$)$ is

$15\mathrm{.}7$ kN$/$m$3.$ Assuming that the specific gravity of solids $($Gs$)$ is $2\mathrm{.}66,$

$$ Calculate the degree of saturation $($S$).$

$$ What is the maximum dry unit weight that can be attained without changing the

moisture content of the soil?
