Determination Of Atomic Weight (1959)
The film demonstrates the determination of the atomic weight of copper through experimental methods. It explains the importance of atomic weights in chemistry and illustrates the process using the law of Dong and Petit, which connects specific heat to atomic weight. The experiment involves measuring the specific heat of copper, calculating its equivalent weight from copper oxide, and determining its valence. The results yield an approximate atomic weight of 67.4 and a more accurate value of 63.72, closely aligning with the accepted atomic weight of 63.57.
