    v = 86.2 mL

    Explanation:

    Given dа ta:

    Mass of ethanol = 68.0 g

    Volume of ethanol = ?

    Density = 0.789 g/mL

    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

    Now we will put the values in formula.

    0.789 g/mL = 68.0 g / v

    v = 86.2 mL
