    Gs = 2.65
    ρw = 1000 kg/m3
    ηa = 0
    w = 10%
    = 0.10

    = 2094.862 kg/m3

    Calculation of Dry Density of Soil

    Given data:
    Specific gravity of solids (Gs) = 2.65
    Mass density of water (ρw) = 1000 kg/m3
    Moisture content (w) = 10%

    Formula:
    Dry density (ρd) = [(1 + w/100)/(1 + e/100)]*ρ/[(Gs/1000) + w/100]
    where
    e = void ratio
    ρ = wet density of soil

    Calculation:
    As per the given data, the soil has zero air voids. Therefore, e = 0.

    The wet density can be calculated as follows:
    ρ = ρw / (1 + w/100)
    = 1000 / (1 + 10/100)
    = 909.09 kg/m3

    Substituting the given values in the formula:
    ρd = [(1 + 10/100)/(1 + 0/100)]*909.09/[(2.65/1000) + 10/100]
    = 2094.862 kg/m3 (rounded off to 1 decimal place)

    Therefore, the dry density of the soil sample with zero air voids and 10% moisture content is 2094.862 kg/m3.
