2 hydrogens, one oxygen in a molecule
so three atoms per molecule
a mol is 6*10^23 molecules
so
18 * 10^23 atoms per molecule
a mol weighs 2+16 = 18 grams
so
(6/18) * 10^23 molecules per gram
so three atoms per molecule
a mol is 6*10^23 molecules
so
18 * 10^23 atoms per molecule
a mol weighs 2+16 = 18 grams
so
(6/18) * 10^23 molecules per gram
