Calculating Empirical and Molecular Formulas
Empirical Formulas are SWEETER! Problem Set
In the scientific investigation that you completed in the previous topic, you calculated the molar mass of a variety of compounds containing wafers and cream. For this problem set, you will use the data you collected about the molar mass of the "cookium" compound, as well as the mass of the wafer and cream atoms, to answer the questions below. Make sure to completely answer each question and to show all of your work.
