A brick has a mass of 4.0 kg and the Earth has a mass of 6.0 × 1027 g. Use this information to answer the questions below. Be sure your answers have the correct numb of significant digits.(a) What is the mass of 1 mole of bricks? Round your answer to 2 significant digits.(b) How many moles of bricks have a mass equal to the mass of the Earth? Round your answer to 2 significant digits.

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.
