Very roughly how many water molecules would you guess there are in a single cell? Within a couple of orders of magnitude? I got it quite wrong.

I guessed a trillion, but only because you said you got it wrong. Then I calculated that a red blood cell weighs about 1.6 trillion times as much as a water molucule, so I'm pretty confident.

Yes; they’re very small for human cells, though. Add an order of magnitude or two to get a typical-sized one.

If you want to visualize 10^14: If a water molucule is a cubic mm (pinhead), a cell's worth would be 10^5 × 10^5 × 10^4, or: 100m × 100m × 10m —an entire city block's worth of three-storey buildings.

Picking a smaller scale: model a water molecule as 1/10 of a mm, about as small a thing as you can see; now 10^14 would take up: 100m^3, or 6m × 6m × 2.75m — about the size of a living room.

I do the mm^3 vs. m^3 visualization every time I try to get a handle on "parts per billion".
