    The density of oak is ranging from 0.6 - 0.9 g/cm³ and the density of given wood is 0.68 g/cm³. The piece of wood is oak.

    Explanation:

    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.

    Given dа ta:

    Volume = 103 cm³

    Mass = 70 g

    Density = ?

    Solution:

    d = m/v

    d = 70 g / 103 cm³

    d = 0.68 g/cm³

    The density of oak is ranging from 0.6 - 0.9 g/cm³. so the piece of wood is oak.
