🔏 (a) How many water molecules are there in your body?
(Assume that you are nearly all water.)

(b) How many drops of water are there in all the oceans of the world?
(The mass of the world's oceans is about 10²¹ kg. Estimate the size of a typical drop of water.)

(c) Which of these two numbers from (a) and (b) is the larger?

🛠 Necessary tools:

🔸radius ~ 1mm
🔸The molar mass of Oxygen is 16 gr.
🔸The molar mass of Hydrogen is1gr.

⚠️The solution is simple but the answer will be surprising.
