Useful Information: The 25.0 wt % ethylenediamine solutioncontains 25.0 % ethylenediamine by mass, dissolved in water, andhas a density of 0.950 g/mL. First calculate the mass of the C2H8N2solution from its volume and density, then calculate the mass ofthe C2H8N2 by remembering that
mass of solute wt % solution = x 100 mass of solution
From their masses and formula weights, you should then compute thenumber of moles of NiCl2•6H2O and of C2H8N2 that were used.(Remember the formula weight of NiCl2•6H2O should include the massof the waters of hydration.)Ă‚Â Ă‚Â
1. Create a typed table that concisely presents the quantities(mass or volume as appropriate for each reagent, as well as molesfor all reagents) and appearance of both of the reactants and thenickel product. (Remember to clearly label the table with a titleand headers for all data columns/ rows. Avoid blank cells in thetable.)
2. What was the limiting reactant for your synthesis? Show yourtyped calculations. 3. What was the theoretical and percent yieldof trisethylenediaminenickel(II) chloride for your experiment? Showyour typed calculations.
4. Assuming all of the limiting reactant was completely consumed(reacted), how many moles of the other reactant (non-limiting)remained? Show your typed calculations.
