(a)
Interpretation:
The copper yield results are lowered by the value 0.5 mg. The percent relative error due to the source is to be determined when the weight of the copper sample is 25mg.
Concept introduction:
The following formula will be used for the calculation of the relative error-
Where,
(b)
Interpretation:
The copper yield results are lowered by the value 0.5 mg. The percent relative error due to the source is to be determined when the weight of the copper sample is 100mg.
Concept introduction:
The following formula will be used for the calculation of the relative error-
Where,
(c)
Interpretation:
The copper yield results are lowered by the value 0.5 mg. The percent relative error due to the source is to be determined when the weight of the copper sample is 250mg.
Concept introduction:
The following formula will be used for the calculation of the relative error-
Where,
(d)
Interpretation:
The copper yield results are lowered by the value 0.5 mg. The percent relative error due to the source is to be determined when the weight of the copper sample is 500mg.
Concept introduction:
The following formula will be used for the calculation of the relative error-
