Show the calculation to determine the grams of Ni 2+ in your Ni-en complex you analyzed. Figure out where the equipment for the lab is kept someof it will be in the cabinet, some of it will be on the cart. Site Use The information contained on this Web Site is provided for informational purposes only. Hexane's molecular formula is C6H14, and its empirical formula isC3H7, showing a C:H ratio of 3:7. If the compound contains oxygen as well as carbon and hydrogen, calculate the mass of the oxygen by subtracting the mass of carbon and hydrogen from the total mass of the original sample of compound. Record the number on the bag in the data table.

As you progress further in science, you will see variations in styles of lab reports, though they all contain the same basic principles. When a droplet of water touched the glass, it dispersed immediately. It could be used as a qualitative test: does the indicator solution change color when a drop of sample is added? Give an experimental section for this laboratory experiment. Background: We have been talking about the uses of the formulas of compounds as well as how to determine the simplest empirical formula of a compound based on chemical analysis.

The general procedure is to use laboratory techniques to determine the mass of each element in the compound. This would be a problem because the soot left on the crucible would vary from our constant. Solution As for all reaction stoichiometry calculations, the key issue is the relation between the molar amounts of the chemical species of interest as depicted in the balanced chemical equation.
