minus-squareKayel@aussie.zonelinkfedilinkEnglisharrow-up24arrow-down1·edit-21 year agoIgnoring 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
