How to calculate the empirical formula of copper(II) sulfate hydrateThis video will explain how to calculate the formula of copper(II) sulfate hydrate from the mass data measured in lab.
How to analyze the data for this lab:Data analysis is the math that is done to the raw data. Raw data is data obtained in lab and should not be referred to in the accept or reject claim section. Only analyzed data should be referred to in the accept or reject claim section.
What should be in the data analysis section:
After calculating the empirical formula of the copper (II) sulfate hydrate, analyze this data using percent composition. The ratio is 1 mole copper (II) sulfate to 5 moles water. Five should be used as the theoretical value in the percent composition calculation and the number you calculated from your lab data should be used as the actual or experimental value.
