About Five Times As Many Drops of Water In the Ocean As Molecules in A Cup of Water

About Five Times As Many Drops of Water In the Ocean As Molecules in A Cup of Water

Or about 1/5 the number of molecules in a cup of water as drops of water in the oceans.

A glass of water, or 200 grams of water, therefore contains 6.6855 × 10e24 water molecules.
3.25 × 10^25 drops of water in the oceans. 

3.25e25 / 5 = 6.5e+24

A mole is defined as Avogadro's number of particles of any kind of substance (atoms, molecules, or ions). Avogadro's number is approximately 6.022 × 10e23. Thus 18.01508 grams of water contain 6.022 × 1023 water molecules. A glass of water, or 200 grams of water, therefore contains 6.6855 × 10e24 water molecules.

The mass in grams of one mole of water, that is, the volume of water containing 6.022×10e23 molecules (the so-called Avogadro constant), is: 2 × atomic weight of hydrogen + atomic weight of oxygen, since each molecule contains two hydrogen atoms (H) for each oxygen (O).

If we define a drop as 1cm^3.
And since the volume of Earth's oceans is 1.332 billion km^3.
There are approximately 133,200,000,000,000,000 drop of water in the sea.
One hundred and thirty-three quintillion two hundred quadrillion.
How many drops of water make up the sea? - Quora
https://www.quora.com/How-many-drops-of-water-make-up-the-sea
There is about 1.3 x 10^9 billion cubic kilometers of water in the oceans. There are 1.0 × 10^15 cubic centimeters in 1 cubic kilometer. There are 25 drops of water in 1 cubic centimeter.

Multiple those three numbers together, and you get 3.25 × 10^25 drops of water in the oceans. 

Hope that helps!
