Brande also described some pure salts of lithium, such as the chloride, and, estimating that lithia (lithium oxide) contained about 55% metal, estimated the atomic weight of lithium to be around 9.8 g/mol (modern value ~6.94 g/mol).
Brande juga menjelaskan beberapa garam murni litium, seperti klorida, dan, memperkirakan bahwa lithia (litium oksida) mengandung logam sekitar 55%, memperkirakan berat atom litium pada kisaran 9,8 g/mol (nilai modern ~6,94 g/mol).
