-
- Within a few thousands of a gram, 1 mol of protium atoms (protium=hydrogen
- w/ 1 proton and 0 neutrons in the nucleus, by far the most common variety)
- has a mass of 1 gram. 1 mol of H atoms has 6.02x10^23 atoms, so 1 atom
- has a mass of 1 g per mol / 6.02x10^23 atoms per mol = 1.66x10^-24 g.
