Suppose a student started with 129mg transcinnamic acid and 0.50ml of 10% bromine solution and after the reaction and workup ended up with 0.216g of brominated product. Calculate the student's theoretical and percent yield.
My calculation
0.50ml x 10% = 5ml
And then 0.126g change 216mg
Who helps me to solve it for me. Step by step.

I did a similar problem last Friday. Just change the numbers to suit your problem. Follow the steps.
