Question

Three compounds containing potassium and oxygen are compared. Analysis shows that for each 1.00 g of O, the compounds have 1.22 g, 2.44g, and 4.89 g of K, respectively. Show how these data support the law of proportion.

Answer 1

Each compound should have KO2, which would imply a mass of 39.0983 for K, and 32 for O2. The proportion to each other is 1:1.22. The next compound should be K2O2, the next K4O2.
