SUMMARY
John Dalton's atomic weight values were derived from his analysis of gas mixtures, specifically using ratios of compounds such as carbon monoxide (CO), carbon dioxide (CO2), and copper carbonate (CuCO3). Dalton incorrectly classified water as a binary compound of hydrogen and oxygen, as well as ammonia. These misconceptions impacted his calculations, leading to inaccuracies in some of his atomic weight determinations. Further exploration of Dalton's work reveals both his methodologies and the errors present in his conclusions.
