During construction of a highway project, a soil sample was taken from compacted earth fill for a sand-cone in-place density test. The following data were obtained during the test: 1. Weight of sand used to fill test hole and funnel of sand-cone device \( =845 \mathrm{~g} \). 2. Weight of sand to fill funnel \( =323 \mathrm{~g} \). 3. Unit weight of sand \( =100 \mathrm{lb} / \mathrm{ft}^{3} \). 4. Weight of wet soil from test hole \( =648 \mathrm{~g} \). 5. Moisture content of soil from test hole \( =16 \% \). Calculate the dry unit weight of the compacted earth fill.
