of
a
substance
in
a
chemical
reaction.
The
percentage

of
the
reaction
is
76%.
Determine
the
real
yield
of
the
reaction.
Give
your
answer
to
3
significant
figures.

Answer 1

To determine the real yield of the reaction, we can use the following formula:

Real yield = Theoretical yield * Percentage yield / 100

where:

Real yield is the amount of product actually obtained in the reaction.

Theoretical yield is the maximum amount of product that can be obtained from the reaction, based on the balanced chemical equation.

Percentage yield is the percentage of the theoretical yield that is actually obtained in the reaction.

We are given that the chemist wants to make 216g of the substance, which is the theoretical yield. The percentage yield of the reaction is 76%, so we can calculate the real yield as follows:

Real yield = 216g * 76% / 100 = 165g

Therefore, the real yield of the reaction is 165g, to 3 significant figures.
