What if a chemical reagent reports purity as a range?

  1. Dec 8, 2016 #1
    I have a chemical reagent that says:

    Assay ... 93.0 ~ 103.0%

    Which value should I use in theoretical computations? Should I take the average or the lowest value?

    Depending on the circumstances I would either go for the average, or I would calculate for both ends separately to report the final result of my calculations as a range as well.
