A student synthesized caffeine during an experiment. He had expected 10.0 grams of caffeine, but was only able to collect 4.72 grams. What was the percent yield for this experiment?

47.2%

Explanation:

Judging from the question given, the theoretical yield is 10g because the student had already made his/her calculation and was expecting to get the same result at the end of the experiment. But he could only get 4.72g from the experiment.

Now, The percentage yield can be obtain as follows

Experimental yield = 4.72g.

Theoretical yield = 10g

%yield = Experimental yield /Theoretical yield x100

% yield = 4.72/10 x100

%yield = 47.2%

Therefore, the percentage yield of the experiment is 47.2%

did anyone actually do this? like if anyone has submitted this i rly need .
