How many moles of water are in an olympic swimming pool?

Answer 1

An Olympic swimming pool holds about 2,500 cubic meters of water, which is equivalent to 2,500,000 liters. Since one mole of water (H₂O) is approximately 18 grams and one liter of water has a mass of about 1,000 grams, this means there are roughly 2,500,000 moles of water in an Olympic swimming pool. Thus, you can estimate that there are around 138,888,889 moles of water in such a pool.
