Answer: The percentage yield of
is 90.26%.
Step-by-step explanation:
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of
= 80 g
Molar mass of
= 100 g/mol
Plugging values in equation 1:
For the given chemical equation:
By the stoichiometry of the reaction:
If 1 mole of
produces 1 mole of
So, 0.8 moles of
will produce =
of
Molar mass of
= 44 g/mol
Plugging values in equation 1:
The percent yield of a reaction is calculated by using an equation:
......(2)
Given values:
Actual value of
= 35.2 g
Theoretical value of
= 39 g
Plugging values in equation 2:
Hence, the percentage yield of
is 90.26%.
