<u>Answer:</u> The percentage yield of
is 90.26%.
<u>Explanation:</u>
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%.

Answer: A. inconsistent data
Indeed, using inconsistent data in a research or more to support an argument will only jeopardize its validity. A scientific argument supported by inconsistent data will be considered invalid and unreliable. That's why there are several scientific ways on data gathering.
