Which is more?
The glass
8.4septillionwater molecules in 250 milliliters
One mole of water weighs 18 grams and contains just over 602 sextillion molecules. A glass with 250 grams of water is almost 14 moles. That's about 8.4 septillion molecules – 84 followed by 23 zeros.
The oceans
5.3sextillionglasses of 250 milliliters
The world's oceans hold about 1.3 billion cubic kilometers of water. A cubic kilometer is a trillion liters, so four trillion glasses. Altogether about 5.3 sextillion glasses – 53 followed by 20 zeros.
Not a close race
The molecules win about 1,500 to 1. If you poured a glass of water into the sea and mixed it well, every glass taken from the sea would again contain some of your molecules.
