Answer:
a) is the mass of 1 mole of bricks.
b) moles of bricks have a mass equal to the mass of the Earth.
Explanation:
a) Mass of brick = 4.0 kg
1 mole = particles/ atoms/molecules
Mass of bricks :
is the mass of 1 mole of bricks.
b)
Mass of the Earth = M =
Mass of 1 mole of brick = m=
Let the moles of brick with equal mass of the Earth be x.
moles of bricks have a mass equal to the mass of the Earth.
