How many?
(lemmy.ca)
That took me too long.
H~2~O ...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.
Hey guys, look at this big dumb dumb. He's never seen the moon before! There's obviously two stars in the sky
But the moon and the sun can't be in the sky at the same time. Otherwise it would be night time in the day!
Actually, if it's a new moon, they can.
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‽
I wish people would stop pretending like we live on a ball orbiting a star. We live on a disc, and Australia is on the tails side, and we each have a star, like a sexy flaming-ball-of-gas Sandwich..
÷
Exactly!

The monster math?!
It was a classroom smash.
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!
The funniest part is nobody officially recognizes this as a name.
Define nobody. I've heard this joke from at least high school and I'm over 40. My teacher pulled it on my class, and probably every class he had.
Go to any institution and scientific journal. You will never see this name. Nobody uses it aside from like you just said jokes and whatnot officially its never used. It's scientific name is water. Good luck finding this in anything published for peer review.
Ah, I didn't realize you meant it that way. I have no argument against that, nor do I desire to have one.
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 * 10^23 atoms/mol = 8.33 * 10^24 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"
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.
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.
There are more reposts of this meme than there are stars in the entire Solar System.
Who else counted the fingers before reading the text? I save you the hassle, it's 5.
Toyota hydrogen V8 for the win !!!
