Question # 1

By Rahul Goel & Tanvir Niaz

Our Question

A mole of Big Macs Stacked up would reach from the Earth to the Moon and back how many times?

Measurements

A Big Mac has a height of 5 cm ( 2 inches) The distance from the centre of the Earth to the

Moon is 384, 403 km Radius of Earth is 6378.1 km Radius of Moon is 1737.4 km Avogadro’s formula is 6.022 x 1023

Calculations

Distance from surface of Earth to surface of Moon = 384, 403 – 6378.1 – 1737.4 = 376287.5 km

376287.5 km x 100 000 = 37 628 750 000 cm Distance from the Earth to the Moon and back is 37 628 750 000

cm x 2 = 75 257 500 000 cm One mole of Big Macs = 5 x (6.022 x 1023 )

= 3.01100 × 1024 We know the units are the same (centimeters), so now divide

3.01100 × 1024 cm by 75 257 500 000 cm to find the answer 3.01100 × 1024 cm / 75 257 500 000 cm = 4 × 1013

Conclusion

Therefore, a mole of Big Macs can be stacked forty trillion (40, 000, 000, 000, 000) times from the Earth to the Moon and back. THAT IS A LOT!
