Question: Calculate the relative standard deviation in the computed molar concentration of 0.0200 M HCl if this acid was standardized against the masses found in Example

Calculate the relative standard deviation in the computed molar concentration of 0.0200 M HCl if this acid was standardized against the masses found in Example 16-1 for (a) TRIS, (b) Na2CO3, and (c) Na2B4O7 ∙ 10H2O. Assume that the absolute standard deviation in the mass measurement is 0.0001 g and that this measurement limits the precision of the computed concentration.
