Answer:
[tex]2.58 g/cm^3[/tex] is the particle density of a soil sample.
Explanation:
Percentage of Solid space = S%
Bulk density of the solid= B
Particle density of the solid = D
[tex]S\%=\frac{B}{D}\times 100[/tex]
Percentage of Porosity in the solid= P%
[tex]P\%=100\%-S\%[/tex]
We are given , P% = 40%
B = [tex]1.55 g/cm^3[/tex]
[tex]40%=100\%-S\%[/tex]
[tex]S\%=100%-40\%=60\%[/tex]
[tex]60\%=\frac{1.55 g/cm^3}{D}\times 100[/tex]
[tex]D=\frac{1.55 gcm^3}{60}\times 100=2.58 g/cm^3[/tex]
[tex]2.58 g/cm^3[/tex] is the particle density of a soil sample.
