    Answer:

    m=6.85\times 10^{24}\ kg

    Explanation:

    The radius of Earth is 6.67\times 10^6\ m

    The density of an object is given by :

    d=\dfrac{m}{V}

    The density of Erth is, d = 5515 kg/m³

    Where

    m is the mass of the Earth

    So,

    m=d\times V\\\\m=\dfrac{4}{3}\pi r^3\times d

    Put all the values,

    m=\dfrac{4}{3}\pi \times (6.67\times 10^6)^3\times 5515 \\\\m=6.85\times 10^{24}\ kg

    So, the mass of the Earth is equal to 6.85\times 10^{24}\ kg.
