Could you show me the steps to solve this please $($everything needed to complete the question is in the picture attached$)$

Soil sample was collected after conducting in$-$situ bulk density measurement mentioned in question $3$ for determining dry density, dry unit weight, porosity and void ratio of the soil. Following data were recorded after specific gravity measurement $($using gas jar method$)$ and moisture content measurement in laboratory. Determine the dry unit weight, porosity and void ratio of the soil sample.
