    Specific volume= v/m
    V=1*10^-3
    m=8/9.81
    Now, specific volume = 10^-3/(8/9.81)=(9.81*10^-3)/8 = 1.23*10^-3

       Volume = 1 litre = 1 x 10–3 m3, W = 8 N

    Specific Weight = W / V = 8 / 1 x 10–3 = 8000 N/m3

    Specific Weight = Mass density x Acceleration due to gravity

    8000 = ρ x 9.81

    ρ = 8000 / 9.81

    ρ = 815.4944

    Specific Volume = 1 / (Mass Density)

    = 1 / ρ

    = 1 / 815.4944

    = 1.23 x 10– 3 m3/kg
