    Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

    Discussion In this experiment‚ the molar mass of two volatile liquids – methanol and an unknown liquid – were calculated for through the Dumas Method. Initially‚ the sets of Erlenmeyer flasks with aluminum foil and rubber bands were weighed. Next‚ volatile liquids were placed in 125mL Erlenmeyer flasks and covered with aluminum foil‚ but small holes were made into the foil. The flask was then heated in a water bath until all of the liquid evaporated. The flask was then removed‚ and weighed again

    Based on calculations #7 made above for solving the molecular weight‚ it was identified that the unknown liquid was Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due
