How many?
How many?

H2O ...so, 2 hydrogen atoms in one water molecule.
How many stars in the entire solar system ? Well, the answer is one 😋-
Can confirm. When I look up all I see is a single star and it hurts my eyes real bad when I look at it.
-
So there's this giant floating orb in the sky and we're not supposed to look directly at it yet no one questions this‽
-
Good, good, that the best test for star identification
-
You could argue that it's based on semantics, though. If you go by a different definition of star, more colloquially, planets like Venus and Mars are visible as "stars" in our solar system.

Dihydrogen Monoxide should be banned.

And hydric acid too!

!Hydro homies@lemmy.ml is coming for you

God damn it

Bullshit.
Hydrogen atoms per water molecules: 2
Stars in the solar system: Sol, Neil Patrick Harris, Justin Timberlake, possibly even more...

Ignoring the joke.
A metric cup is 250 ml.
250 ml = 250 g (the density of water is intentionally 1.000 g / ml)
Water ~= 18 g/mol ( H 1.008 g/mol, O 16.something g/mol)
250 g / 18 g/mol = 13.8 mol
13.8 mol * 6 * 1023 atoms/mol = 8.33 * 1024 molecules of water
And there are two atoms of H in one molecule of water, so 1.66*10^25 atoms of hydrogen in a glass of water.
That's a lot
-
The craziness thing about all of this is that there is actually such a thing as "a metric cup"
-
It's crazy how much stuff is out there. https://www.universetoday.com/36302/atoms-in-the-universe/

-
At least twice as much!
-
There's also more hydrogen in a glass of water than oxygen.
-
Only if you're counting atoms. There's more oxygen by weight.
-
Don't mol shame.

-
There are more reposts of this meme than there are stars in the entire Solar System.
-
Well, that’s true in our solar system.
-
Ours is the only Solar System, named after our star Sol. Others are generically called star systems or stellar systems.

Who else counted the fingers before reading the text? I save you the hassle, it's 5.

Toyota hydrogen V8 for the win !!!
-
Did they read “a mole” and misinterpret it as “molecule” when writing the headline?
-
The solar system only has 1 star, so it's accurate
-
-
I get the joke, but from the earth looking out, the other planets are all stars as well.
-
Not exactly. Stars twinkle; planets don't. That's the easiest way to tell if you're looking at a star (other than our own of course) or a planet reflecting light.
-
Might depend on language also. Being a weeb, my example is going to be Japanese, where Hoshi(星) can mean both star and planet.
Looking in wiktionary, sometimes this can be translated more to "heavenly body" but the source seems to have been about twinkling things in the sky. Still, I've definitely heard what would translate to "this star" being used for the planet the speaker lives on.
Edit: also, the first time I spotted Jupiter with my telescope I thought it was a bright star with 2 dimmer stars around it. I changed my zoom, took pictures, and zoomed in before I realized it was Jupiter and it's largest two moons. People with worse tech wouldn't have thought " oh, that one doesn't twinkle".

Alright, I know where they went wrong here. There are more hydrogen atoms in a glass of water than stars in the universe.
There are about 1.58 x 1025 hydrogen molecules in 8oz of water, and there are an estimated 1022 - 10^24 stars in the universe.
