Weight$-$Volume Relations Problems $($Course Objective $2)$

A CH soil has a degree of saturation $($S$)$ less than $100\%,$ a moist weight $(W)$ of $12\mathrm{.}20$ lb $,$ a

total volume of $0\mathrm{.}10f{t}^3,w=12\mathrm{.}0\%$ and specific gravity of solids $(G_s)$ of $2\mathrm{.}72.$ Find: moist unit

weight $({}_m)$; dry unit weight $({}_d)$; void ratio $($e$)$; porosity $(n)$; volume of water $(V_w)$; and $S.$
