    Benzene is more denser.

    Explanation:

    Given dа ta:

    Mass of ethanol = 3.9 g

    Volume of ethanol = 5 mL

    Volume of benzene = 5.0 mL

    Mass of benzene = 4.4 g

    which is denser = ?

    Solution:

    Density:

    Density is equal to the mass of substance divided by its volume.

    Units:

    SI unit of density is Kg/m3.

    Other units are given below,

    g/cm3, g/mL, kg/L

    Formula:

    D=m/v

    D = density

    m=mass

    V=volume

    Symbol:

    The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

    Density of ethanol:

    d = m/v

    d = 3.9 g / 5 mL

    d = 0.78 g/mL

    Density of benzene:

    d = m/v

    d = 4.4 g/5.0 mL

    d = 0.88 g/mL

    So benzene is more denser.
