Following are the results of a field unit weight determination test on the same soil with cone method:

Calibrated dry sand of Ottawa sand $=87\mathrm{.}4pcf$

Calibrated mass of Ottawa sand to fill the cone $=750g=1\mathrm{.}6516$

Mass of jar $+$ cone $+$ sand $($before use$)=7500g=16\mathrm{.}5lb$

Mass of jar $+$ cone $+$ sand after use
