Sample Math Problem
from this job:
During an experiment to make
a compound, starting materials,
A and B, are put together to
create a reaction to produce
material C. If all of A and B and
transferred to create C, then
the yield of the reaction is
100%. However, it is not
possible to get 100% of yield in
an experiment. The problem is
to solve how much of C was
actually created from A and B.
The closer the percentage is to
100%, the better reaction
conditions there are.
