Dalton's atomic weight problems
Dalton's atomic weight problems
Dalton assumed a combining ratio of hydrogen to oxygen atoms of 1:1.Data at the time suggested that the mass ratio of hydrogen to oxygen in water was 1:7. Taking the atomic weight of hydrogen to be one, that of oxygen was seven.
Modern data indicate that the combining ratio of hydrogen to oxygen atoms is 2:1 and that the mass ratio is 1:8 (or 2:16).
If the atomic weight of hydrogen is taken to be one, that of oxygen must be 16.
