How Big is a Mole? If an Avogadro number of pennies were distributed evenly among the approximately 5 billion inhabitants of earth, each man, woman, and child would have enough money to spend a million dollars every hour - day and night – and still have over half of it unspent at death.
How Big is a Mole? If one mole of particles the size of sand grains were released by the eruption of Mount St. Helens, they would cover the entire state of Washington to the depth of a ten-story building.
How Big is a Mole? Water flows over Niagara Falls at about 650,000 kL (172,500,000 gallons) per minute. At this rate, it would take 134,000 years for one mole of water drops to flow over Niagara Falls.
How Big is a Mole? One mole of marbles, each 2 cm in diameter, would form a mountain 116 times higher than Mount Everest. The base of the marble mountain would be slightly larger than the area of the USA. Note: Marbles are assumed to have hexagonal closes packing and the mountain has a cone of angle 30 degrees. Area of USA = 9.32 E6 km2.
How Big is a Mole? One mole of moles (animal-type), placed head to tail, would stretch 11 million light years and weigh 9/10 as much as the moon. Note: Each mole is assumed to be 17 cm long with a mass of 100g. Speed of light = 3 E8 m/s. Mass of moon = 6.7 E22 kg.
How Big is a Mole? One mole of marshmallows would cover the USA to a depth of 105,000 km (6500 miles). Note: the volume of a marshmallow is estimated as 16 cm3. The area of the USA is 9.32 E 6 km2 or 3.6 E6 mi2.
