In a field density test using the oil method, the wet mass of the soil removed from a hole in

the compacted fill was $1\mathrm{.}61kg.$ The mass of the oil required to fill the hole was $0\mathrm{.}81kg$ The

specific gravity of oil $(G_{\text{o}\text{i}\text{l}})$ is $0\mathrm{.}9.$ the field water content was $26\%.$ The specific gravity of

the soil solids $($Gs$)$ is $2\mathrm{.}7.$ Calculate the dry density and degree of saturation of the

compacted soil.
