How do I resolve this yield question?
« on: April 19, 2016, 03:02:57 PM »
If you use 6mL of styrene to prepare polystyrene what would be the expected yield? Explain.

That is all that's given and I have no idea how to resolve this.

I feel like there's way more information I need. It could be based on the experiment I did in the lab where we used 1ml instead of 6 and the end result the polystyrene weighed about 3mg.

If that were the case, how do I tie it into the yield equation?

Expected == theoretical. Can you write an equation for the reaction?

Your value of the actual yield (3 mg) can be used to calculate the percent yield.  But before you do that calculation, you must complete the theoretical yield calculation.  I agree wit sjb about writing an equation.  I also suggest that you will need to convert your volume (6 mL) into a different unit of measurement.
