SUMMARY
The discussion focuses on determining the formula of a hydrate based on its percent composition: Pb=54.61%, C=12.66%, H=1.61%, O=16.88%, and H2O=14.24%. To find the hydrate formula, one must convert the percentages into moles by dividing each percentage by its respective molar mass. The participant suggests treating H2O as an element with a molar mass of 18.02 g/mol, which constitutes 14.24% of the hydrate. This method leads to the identification of the hydrate's empirical formula.
