    Mass of 1mole of brick = mass of 1 brick x avagadro number

    = 4 kg x 6.022 x 10^23 bricks = 2.4 x 10^24 kg

    No. of moles of bricks have a mass equal to the mass of the earth

    = mass of earth / mass of 1 mole of brick

    = [ 6 x 10^27 ] / [ 2.4 x 10^24 ]

    = 2.5 x 10^3

    = 2500 moles
