Question

Which formula can be used to calculate the theoretical yield?

Actual yield + percent yield
Amount of reactants + amount of products
(Actual yield ÷ percent yield) × 100
(Amount of reactant ÷ amount of product) × 100

Answer 1

C

Step-by-step explanation:

Just took the test :)

Answer 2

Option C, (Actual yield ÷ percent yield) × 100

Step-by-step explanation:

Theoretical yield is defined as the total amount of product formed for given reactants in a chemical reaction. It is an ideal case which assumes no exceptions or wastage.

The mathematical relation between the actual yield, percent yield and theoretical yield is as follows -

`P.Y. = (M_(A.Y.))/(M_(T.Y.)) * 100`

Where

P.Y. represents the percent yield a

M A.Y. represents the mass obtained from actual yield

M T.Y. represents the mass obtained from theoretical yield

Hence, if we rearrange the formula, we get -

`M_(T.Y.) = (M_(A.Y.))/(P.Y.) * 100`

Hence, option C is correct
