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”
That took me too long.
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 10^25 hydrogen molecules in 8oz of water, and there are an estimated 10^22 - 10^24 stars in the universe.
Edit: super script markdown wasn’t working
a hydrogen molecule is H2, this is about water
Is it wrong? I’ll do some complex math, so feel free to ask follow up questions.
Hydrogen atoms in one molecule of water: 2
Stars in the entire solar system: 1
2 is larger than 1 [citation needed]
