$3.$ An SM soil from the $17$th St$.$ Canal project in New Orleans has a natural water content of $23\mathrm{.}40\%,$ Gs$=2\mathrm{.}68,$ and a total unit weight of $125\mathrm{.}4$ pcf$.$ The void ratios corresponding to the densest $($emin$)$ and loosest state $($emax$)$ of the soil are $0\mathrm{.}51$ and $0\mathrm{.}74,$ respectively. Find the relative density, void ratio, and degree of saturation.
