What is the theoretical yield and limiting regent for this reaction? 25 mg Trans-1-2,dibenzoylethylene + 3.0ml Methylene Chloride?
MW for trans-1-2: 236.27 g/mol
MW for methylene chloride: 84.93 g/mol

Also, how do you find moles in a liquid such as methylene chloride? I got 0.047, but I'm not sure its right.

I got 0.047 moles, also.

Okay, so thats 47 millimoles of Methylene Chloride. And 0.42 mmol of 1-2DIbenzoylethylene. Making Methylene Chloride my limiting reagent with a theoretical yield of 0.099g?

anonymous · Answer

No, I get .106 mmol of 1-2 dibenzoylethylene [(0.025 g/236.27 mol)*1000].  I think the limiting reagent will be the other reactant.

anonymous · Answer

Oh wait I'm sorry, thats 100mg of trans-1-2 diebzoylethlene making t 0.42mmol

anonymous · Answer

Ok, then you would be correct.

anonymous · Answer

Great, thanks for making it clear. For some reason I can't get this to stick in my head.

anonymous · Answer

As crazy as the numbers get, I don't like working in millimoles, maybe it might help converting to moles?
