Molecules and grams math question

[JustinS]

Question:
Amount of water on Earth is 1.4x 10^24 grams.
Dan weighs 70kg
60% of Dan is H2O
Dan drank 180ml of H2O/Hemlock
All H2O Dan drank has dispersed evenly throughout Earth.
how many water molecules are in your body that are from Dan’s Hemlock?

Assume your weight is 70kg and 60% of your body is H2O.

There are many ways to approach this; it is clearly intended as practice in thinking through a problem involving many parts, so I would only want to provide small hints, and let you do the rest for experience.

Have you thought about the ratio of the water in Dan's drink to the water in the entire world?

And have you considered that not all of the information given may be needed?
