The mass of 1 mole of bricks is about 2.4 × 10²⁴ kg
2500 moles of bricks have a mass equal to the mass of the earth
<h3>Further explanation</h3>
This problem is about mole.
1 mole ≈ 6.0 × 10²³ particles
1 mole of bricks ≈ 6.0 × 10²³ bricks
Mass of 1 brick = 4.0 kg
Mass of 1 mole of bricks ≈ 6.0 × 10²³ × 4 kg = 2.4 × 10²⁴ kg
Number of moles of bricks that have a mass equal to the mass of the earth could be calculated as follows.
n = Mass of the Earth ÷ Mass of 1 mole of bricks
n = (6.0 × 10²⁷) ÷ (2.4 × 10²⁴)
n = 2500
