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.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

lol idk man i guess u gotta ask bill nye the science guy
