Given the specific gravity of soil solids \( 2.75 \), calculate the zero-air-void unit weight in \( \mathrm{kN} / \mathrm{m}^{3} \) for a soil with moisture content \( 5 \%, 8 \%, 10 \%, 12 \% \) and \( 15 \% \). For this soil determine the variation of dry density \( \left(\mathrm{kg} / \mathrm{m}^{3}\right) \) at \( 10 \% \) and \( 15 \% \) for degree of saturation at \( 80 \%, 90 \% \) and \( 100 \% \)
