    Question

    What will be the percentage of porosity of a soil which

    has 1.5g/cm³ bulk density and 2.65 g/cm³ particle density?
    A 36 Correct Answer Incorrect Answer
    B 38 Correct Answer Incorrect Answer
    C 40 Correct Answer Incorrect Answer
    D 42 Correct Answer Incorrect Answer

    Solution

    Porosity (%) = [(Particle Density - Bulk Density) / Particle Density] x 100 Given: Bulk Density = 1.5 g/cm³ Particle Density = 2.65 g/cm³ Porosity (%) = [(2.65 - 1.5) / 2.65] x 100 Porosity (%) = (1.15 / 2.65) x 100 Porosity (%) = 0.434 x 100 Porosity (%) = 43.4%
