The laboratory exercise calls for transferring 11 – 12 mmol of copper(II) chloride dihydrate to the 125mL Erlenmeyer flask. Determine the molar mass for this reagent (show your work, compare this result to a suitable reference source properly citing the source) and the mass needed to obtain the desired amount.
What is the theoretical yield of the synthesis of bis(acetylacetonato)copper(II) if 4.1962g of the starting material was transferred to the Erlenmeyer flask? (Hint: determine the stoichiometric equivalencies of the reagents in order to determine the limiting reagent)
