ChemistryPrinciples of Instrumental Analysis(a) Interpretation: The minimum weight of the sample for relative error due to 0.5 mg loss to be less than 0.1% needs to be determined. Concept introduction: The minimum weight is calculated by the relative error formula which is given below- E r = E m − E t E t × 100 Here, E r = relative error E m = measured value E t = true valueStart your trial now!
